1941 30 Cwt F-30 ambulance

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.

Very interesting thread and most interesting truck.

There are indeed several photos of 12 and 13 cab trucks coming off the line together. Up until this thread was posted I assumed the date to be late February early March 42 for 13 cab main line production. I wonder if Ford and Chevrolet perhaps had a different phased time scale for the change over ??

So, the 42 engine would be (correct me if I am wrong) the Hydrovent speced engine? (along with rear main seal etc)and just because it was referred as the 42 engine, doesn't mean it was first used Jan. 1 1942. It had just come on line as the previous model had been used up. Does that sound about right?
