Ford Parts Lists describe the "New Design Cab" as being from Serial No 21566.

But "3G" engine on a 1941 build plate? How can that be swapped around?

Thanks for the confirmation Tony. I was going to grab my parts list to find that reference. Good to have a date against an early serial number.

But "3G" engine on a 1941 build plate? How can that be swapped around?

Interested to learn what 3G stands for - would that be an engine built in 1943?

The 3 has been thought to represent a late half of the year design or release (1942) for the next year's production (1943).

So this engine number has appeared a good 12 months earlier than expected.

Thank you all for the comments . Tony , can you translate that in plain english please ? I mean the 3 G thing . What i know and have seen : I was all over that truck and towed it 150 Km to my shop. The cab is a 13 . The engine house is original to the truck and the data plate is original to the engine house . The data plate has never been removed . There is evidence of a hole in the rear of the cabin and a corresponding one on the box to pass wires or hot water hoses . The ambulance house is not original to the truck and was bought seperately . I have spoken to the seller who is a respected member of this group. There is no doubt it’s a 30 Cwt Dec 23 1941 AMBU Cab 13 truck as far as i am concerned . When did Ford stop making 30 Cwt trucks ? Rob Love said previously that according to his reading of the design records he expected Cab 13 ´s production started in December of 41. Time to chime in Rob ? This is getting interesting !

The cargo box on this truck used to be my daughters playhouse back in the late 90s before I sold it on to the present owner.

Re the date, I will have to look again at the Cab 13 in the Design Records, but I am certain it was December of 41. The 3G engine is puzzling. I guess what we need is someone who has Peter Ford's old infoex list to see what the relative chassis serial numbers were at Dec of 41, thus ensuring that this isn't a slip-up of the 41 vice a 42 date.

Ford Army Parts Information Letter AAP6, issued 20 April 1942. This is stated to be applicable to CMP vehicles assembled in Victoria, Australia, so may differ slightly from that of CMPs assembled in other states:

Under the heading 1941 Models:

"Engine Prefix 2G was a 3-3/16 bore (Lorry), 4 speed gearbox lowest engine number 2G219F first assembled January 1941."

The same AAP6 states that the last '1G' prefix engine, serial 1G15318F, was assembled in November 1941.

So a considerable overlap when 3-3/16 bore engines with '1' and '2' prefixes were being assembled to 4-speed Lorry gearboxes.

Why, then, could there not be a similar overlap between '2' and '3' prefixed engines?

3-3/16 bore engines with a 3-speed gearbox (passenger cars and utilities) had a 'D' code eg 2D6128F, the first '2D' engine-gearbox assembled which was in November 1941, hence the letter indicates an engine-gearbox combination, not just the engine, so it stands to reason that the number was assigned at the time the combination was assembled, not when the engine alone was assembled.

The ID plate for the truck indicates that the '3G' prefixed engines were being assembled with the gearbox and the number for the combination assigned prior to late December 1941 in Canada, which would fit if there was a similar overlap to the 1G-2G engine/gearbox assemblies indicated above.

Gents,

3G translates to 1942 model, so it is probably not unusual to find a 1942 model built in late Dec 1941.
