Morris C8 Portee
 

Hello,

I think it is a Morris C8 anti tank gun portee.

Wheels & Tracks No 30 has a good article on these vehicles, which was designed to carry a 2 Pdr antitank gun.

C.S.8/MG or C.S.8/AT

I believe it's a C.S.8/AT anti-tank.

Morris portee
 

I need some explanations about the Morris portee.

According to David Hayward:

1) the original 2 pounder portee was based on the Morris 4x2 CS8 chassis

2) the Morris 4X4 C8/MG was derived from C8/QUAD field artillery tractor

3) the Morris C8/AT 2 pounder portees very similar to the Chevrolet FAT derivatives

On the contrary in the book of Vanderveen the author stated that the Morris Commercial C8/AT was a C8/MG modified to gun tractor.

Was the Morris C8/AT effectively an derived from C8/MG?

The vehicle in the photo of tank museum that i have posted here is more similar to the C8/MG. The shape of the mudguards (three piece flat) is very different from that of Morris CS8


This is an Indian Morris C8/MG

Morris portee
 

On the contrary this is a Morris CS8 portee (with bofors 37 mm)

Any comment is appreciated

Thanks

This is a subject that can really confuse and yet the answers are now to hand. I stand to correction, and am sure I will be, but basically the Morris-Commercial C.S.8T 15-cwt pick-up was built in three early 4 x 2 versions, and various bodies were designed for the basic chassis including cavalry portee. Subsequently Morris Commercial Cars used Continental technology as a basis for their short-lived 'Q' for 'Quad' 4 x 4 system, with front or rear engines, using shafts to each wheel. These were not accepted by the War Department for series production and so MCC developed a 4 x 4 version by 1938 of the C.S.8T as a field artillery tractor, two being built, which were in fact the C.S.8T/FWD to Contract V.3215 of 9 February 1938.

If I may then cheat and quote from my own notes:

The two prototype C.S.8/FWD tractors differed substantially from the production MCC tractors but they were the direct ancestors. Note the different designations as the prototypes [C.S.8/FWD] used a 6-cylinder engine, whereas the production FAT C.8/FWD etc. had a 4-cylinder engine.

Another derivative of the CS.8 4 x 2 was the C8/MG Mobile Gun followed by the C8/AT 2-pounder gun portee. The former had three-piece flat mudguards, whereas the FATs had round mudguards. The /MG and /AT models became obsolete in British service by 1943 and although a large number were sold to New Zealand, many were rebuilt along with the basically similar C.8/P Predictor trucks to C.8/AT Mark III 17-pounder tractors or the airportable version, by MCC at Adderley Park, Birmingham.

The real answer was therefore that the C.S.8T formed the loose basis for derivative 4 x 4 chassis, with the /MG and /AT portees using standard WD-design bodies of which detailed drawings were sent to Canada. Guy designed their Quad-Ant from the 15-cwt 4 x 2 Ant, the C.S.8T rival, and because Guy Motors could not cope with the WD demand for FATs MCC was contracted to build a very similar outline version which was loosely based on the C.S.8T through the wooden-bodied prototype C.8/FWD. In my opinion it was really a case of multiple divergent evolution, and not a strict sequential model development.

As I said, Canada received and binned the pre-war WD 2-pounder drawings. A short time later the WD shipped a MCC C.8/FWD and a Guy Quad-Ant to Ottawa with detailed drawings representing the 4 x 4 FAT design. These were then taken up by GM of Canada with Ford of Canada, and begat the C-GT and then the F-GT. Note I believe that it was this way round! However the 2-pounder drawings were pulled out of the bin and subsequently the DND agreed to a request for a British order for 2-pounder portees and GM of Canada accepted the contract and adapted their C-GT chassis to take a copy of the WD body with a modified #12 open cab which became the # 42 cab. The Portee chassis were interspersed with C-GT chassis on the line in batches though I believe that they lacked the C-GT winch? Comparing serial numbers shows no difference: they had the same model number. It is just possible that Oshawa even converted built-up C-GTchassis on the line. When the Chevrolet 2-pounder portees became obsolete, those not sold to New Zealand were rebuilt, probably by GM Limited in England, to 17-pounder A/T tractors whereas the later # 43 cab C60L 6-pounder portees were rebuilt as G/S trucks with a modified # 43 cab.

See where the KNOWN Portees intersperse. However some of the above may also have been Portees of course.

On another brass plate:
Contract no V.4229, Supply Mech 2028.

Note that the Ministry of Supply placed two contracts: V.4229 was a domestic one, and the overseas order was S/M 2028, the same as for C-GT tractors.

Further, when the Portees were rebuilt to 17-pounder tractors the Census Number prefix changed from 'L' as a 3-tonner truck chassis, to 'H' as a 'tractor'. The C-GT chassis retained the 'H' prefix throughout unless anyone knows of any being rebuilt?

Morris portee
 

Thanks for your informations!

I have a further question:

In a previous thread Shane Lovell

http://www.mapleleafup.org/forums/sh...=morris+portee

reported this document:
AWM 54: 425/116
Australian LO Report No 21 dated 14 May 1941

I asked whether Aust units would receive Morris 4 wheel drive Portees. BRA indicated that they are unsatisfactory and that British units were to be equipped with 3-ton vehicles converted for Portee, on the basis of five per troop. In view of this disappointing situation regarding Morris Tractors it is suggested that we examine also the problem of converting 3-ton vehicles for Portee purposes. Our immediate requirement is of course the refit of 1 A.Tk Regt on a 36 gun basis.

David, do you think that the Morris 4 wheel drive mentioned in this report was the C8/MG?

Thanks

MCC Portees
 

I believe you may be right Attilio...probably C.8/AT though.

C.8/MG versus C.8/AT
 

It appears as though the earlier C.8/MG Mobile Gun hd no winch, whereas the /AT portee had ramps to load the 2-pounder.

New info
 

I have just found out in my notes on the DND papers that you might just find interesting:

It was also envisaged that some of the 51 1938 Chevrolet 15-cwt G/S trucks were to be utilised as A/T Portees!

The body drawings for the Cavalry Portee were entitled ‘body No. 1 Mk. II Schedule S (V) 339', spread over seven sheets. It appears as though the Portee file was under reference H.Q. 38-72-316, Clive, and complied with WD Specification 36B Parts I & IIC.

Does anyone know who actually built the Chevrolet 2-pdr Portee bodies by any lucky chance please?

As an aside and I shall move this bit when the new thread starts, WD Specification 36-B with part II.C was ‘For a 4-wheeled chassis for use as a military load-carrier of 15-cwt. capacity’. Body Specification M.C. 205-A was for ‘M.T. [Motor Transport] Vehicles-Bodies for- General Specification’. The drawing was S(V)411 - Mk. III Body. The Drawing for the Mounting under the body (D.D. (V) 355 )was for ‘Truck, 15-cwt., 4-wheeled, GS Arrangement showing mounting of Marks I and II bodies on Morris-Commercial C.S.8T, Commer ‘Beetle’ and Guy ‘Ant’ chassis’. These were then copied and retained by the DND. So if you wondered why the 15-cwt CMPs had similar bodies to the 15 cwt MCC C8T Series III, Guy Ant et al, well as per the Portee bodies the DND had the detailed specs and drawings to hand.
