OK. There is a key piece missing here.
We are trying to wrap our heads around two examples of 1941/42 Chevrolet trucks assembled in France, perhaps with 1944 dated engines. France fell in May/June 1940! Maybe these vehicles are rebuilds, or assemblies from available surplus, wrecks, parts and wartime KD vehicles, that were being used to jump start French factories and reboot their economy. Whether or not they were LHD or RHD did not matter at all at the time, but getting the country back on its feet did. Maybe we are looking at these two trucks now through a telephoto lens, when a wide angle one would make more sense. David |

Tr
I believe the engine prefix 'TR' would be for a Canadian built engine . From memory many CMPs have the 'R' series engines . My C8 has a TR prefix engine in it , so does this Australian coupe ute

GM (France), Gennevilliers, Paris

I searched for a bit more information and found that “A new plant went into operation at Gennevilliers, France, on the outskirts of Paris, for assembly of completely knocked down (CKD) cars and trucks.” All vehicles assembled there from imported parts were fitted with a General Motors (France) body tag / data plate *) like the one shown above as they are regarded as new vehicles built in France. I reckon GM Overseas Operations regained control over their Gennevilliers plant right after the war, possibly with the aid of the US Army (late 1945, the US Army 1568th Engineer Depot Company was based at Gennevilliers, Paris). GM then started assembly of CKD kits of these Chevrolet (and other) trucks and cars to fulfill the urgent need for vehicles on mainland Europe. The parts for these kits may well have been manufactured in 1944-1945 under US, United Kingdom or Canadian Government contracts, awaiting shipment for assembly overseas. *) the one attached below is identical and is fitted to a 1958 Buick

Great detective work Hanno, as always the information is out there it’s just knowing where to look
Many thanks to everyone for their input on this thread. Dave |

Whilst taking some measurements of the rear diff on the 1542 for another thread I came across this plate attached to one of the differential bolts.
It reads: Rear Axle Assy. Service No 1809572 General Motors Of Canada Does anyone know what this refers to? It wouldn’t be a part no due to being on a removable or equally very losable plate. Dave |

I also found the body plate in the centre of the first cross member right behind the cab so excuse the angle of the photo.
It reads: Wilson Motor Bodies Code & Serial No ULS-2- 255C A link to info on Wilson Motor Bodies: http://www.coachbuilt.com/bui/w/wils...tor_bodies.htm Dave |

GMC 9543 2-Ton truck
Not trying to muddle the water, but compare the Chevrolet 1542 with this 1940 "GMC 9543" 2-Ton truck at the Canadian War Museum.

GMC's could be described as being heavy duty Chevrolet's, the GMC engine is a different beast compared to the basic Chev engine , it is a more refined motor with, I believe, full pressure big ends.

Dave Ashby
Hi Dave, I've been after photos and dimensions of the bumper bracket for the 1533x2. I am currently supporting several builds and this item has come up as a bit of an issue. I believe the 1543 had the same brackets with support bars. Could you do me a massive favour and take some photos of the bumper brackets and how they fit to the chassis and bumper. Some basic dimensions would be great too. Thank you. |

Dave,
Ref your Rear Axle tag from post 36: It appears that the wide variety of "major assemblies" being stored in Ordnance Depots was cause for confusion by 1944. The Canadian Vehicle Manufacturers were evidently tasked to produce identification manuals to aid personnel when attempting to determine the correct application for major assemblies (ie: Engines, rear axles, front axles, transmissions, transfer cases, and steering gear). The two manuals that I have seen are GM Major Assemblies, and Ford Major Assemblies. They include images or drawings which point out the major identification features, the locations of any cast or stamped markings which will aid in identification (ie: gear ratio), and also have data sheets which list all of the components to assist technicians if they needed to convert the major assembly that they had on hand to fit a different vehicle than it was originally intended for. It appears that at about the same time, the manufacturers were instructed to affix metal tags (such as your example) with the part number of the major assembly. I presume this was seen as a more durable form of marking than any other methods that had been previously employed. I believe that a few examples of this type of tag have been discussed previously on this forum. An example that comes to mind was an image of a Windsor Carrier engine bearing one of these metal tags that was found in a CMP. Perhaps someone with easy access to a CMA-02 or FMA-01 can post an image where these tags are explained. Colin |

Dave,
Here are some images from CMA-01. 1809572 is certainly the correct rear axle for a 1542X3, and it is also correct for 1531X8 and 1541X8. Regards, Colin |

And the 1533X2 had a two-speed axle - have you seen this, Charlie?

2 speed axle confirmation.
Hi Colin and Hanno,
That's a brilliant piece of information, clears up one of the main controversies of the 1533X2 over the years. Slowly filling the gaps in the specification. Only need to find the bumper brackets and the fuel tank cover for the CMP seats (most LRDG trucks had a metal cover on the fuel tank that raised the rear of the fuel tank frame to allow 2 CMP seats to be fitted, possibly because supplies of bench seats ran out?). Thank you again. Charlie |

Hi Charlie, I’ll be up the workshop this week so will get the bumper bracket details you’re after with some accompanying photos.

Dave ,
That would be great, I can't find anything about them anywhere. I've got period photos that confirm the rough shape, but no details of how they look at the chassis end or what format/shape/design they are where they connect to the bumper. I imagine there's a front plate on the bracket, but how wide, what support/bracing it has, how many holes, are all unknown. Likewise the support rod system, and how that attaches to the bracket, the size and shape of the holes in the panel below the grill, (or maybe in the fenders), and whether the support rods are straight or angle into the mounting brackets. Thanks for your help! |

Hi Dave,
Sorry to hassle you, but have you had a chance to take the photographs of the bumper brackets and support rods yet? Any dimensions would be great too. Its one of the last pieces of information that I need to finally come up with a accurate description / specification of the 1533x2 truck and its also a very new bit of information, to me anyway!

Bumper Brackets
Dave Ashby has sent me the photos of the bumper brackets and support rods with some dimensions, and asked me to post them here for everyone to see. They are the same as the Brackets on the 1533X2 LRDG truck and I will post them on the appropriate thread for the 1533X2 truck, for those looking specifically at that truck. Note the thinner near vertical rod supporting the bottom of the grill in photos 4 and 5. Thank you Dave.
Hopefully Colin Alford has some drawings of this area in one of his manuals to get more details. Also I'd be really interested in seeing the steering gear information from the Major Assemblies catalogue for the 1542/3 and 1533X2 trucks, hint! 2 more photos in the next post! Charlie |

Gents,
Over the past couple of weeks, I have been attempting to understand the differences between the various Chev MCP models which is certainly not an easy task. I now understand why there are questions regarding Dave’s truck, and the essentially identical truck that was formerly a museum piece. I think we can all agree that these two trucks appear to have been assembled post-war in France. It appears that they were assembled with a mix of parts from 1542, and 1543. The first serious issue with the data plates showing Model 1542, is that 1542 means 2 ton, 160” wheel base, chassis with cowl. A 1542 should not have a complete factory built cab! The only 160” wheel base MCP with a complete cab should be a 1543 (this may explain why the museum used the designation 1543). While some early 1543s were fitted with the same 20 x 6 wheels as these two trucks, they were all prior the serial number 1154305001 (the 5001st vehicle in 1941). All MCP 1543 used a two-speed rear axle, while these two trucks have single speed rear axles (Dave’s is definitely a Canadian built rear axle correct for a 1542) The front bumper on the two trucks is correct for a 1543X2 and 1533X2, but they do not appear to be correct for 1542. This particular bumper went through three obvious changes on 1543X2. Prior to serial number 1154305001 there was no radiator crash guard (or the mounting holes for same), and there were no large holes in the end for the reflectors. At serial number 1154305001, the crash guard and reflectors were added. At serial number 3154300001, the reflectors were deleted, but the crash guard remained. I believe we are seeing the third type (after 3154300001) because although the crash guards are not present, we can see that the mounting holes are there. According to the parts list, 1542 should have a civilian type bumper. The park lights on top of the headlights: They were not fitted to MCP 1543X2, but they were fitted to those 1542s which were not equipped with blackout equipment (no specific serial number break point). Front axle: 1543X2 after serial number 1154305001 had front axles with the larger War Department standard bolt circle which would not accommodate the earlier Chev wheels. 1542s retained the Chev bolt circle throughout production. 1542 prior to serial 4154200001 had front axles with 26 11/16” Spring centres. After serial number 4154200001, the axle was changed to have a spring centre of 28”. To accommodate this change, the frame remained unchanged, but new front spring mounts, and new springs were used. The reported serial numbers of these two trucks ideally points to having front axles with 28” spring centres. While the chassis of these two vehicles may well have left Oshawa as model 1542s during 1944, they appear to have been assembled in France with a mix of parts from 1543X2 (complete cab, raised bumpers and possibly the rear body). |
