serial # help

[Dave Schindel]

Hi guys, I finally found the serial number for my F15a. Stamped into the LH side of the frame was 1G-10581F. can anyone point me to a data base or decipher the number for me? it is a cab 11 but that is about all I know. Thanks in advance for any help.

I take it the number was on the left frame just under the passenger door.

1 means it was 1940 production and the G might mean government, but I'm not certain on that. The 10581 will be the sequential number of all vehicles produced, so your is the 10581st CMP. I have seen it listed that the F meant right hand drive. Is there an asterisk after your serial number? That was to prevent the used car salesmen from adding extra digits to the end.

My first CMP that I restored was a F15A Cab 11 with serial number 10515, so about 66 vehicles before yours.

It's the engine number.

1G = 3-3/16 bore 95hp V8 engine coupled to a 4 speed lorry gearbox.The 1 means a 1940 model/production year (which does not correspond to a calendar year).


10581 = sequential number of the engine (not the truck). 1G7F was produced in Feb 1940, 1G15318F in November 1941.

F: Foreign to Canadian or US domestic production, which in effect means they are used in right hand drive vehicles.

Rob, there was a figure after the F but I can't tell if it is a star or something else.And yes,it is on the left frame rail below the pass. door. So should the number on the frame match the number on the block providing the engine has not been changed?

[Mike Cecil]

Yes, when the engine was installed on the production line, the engine number was stamped into the chassis rail, becoming the de-facto chassis number. It seems to have been the Ford way: you can see it also on Ford GPW and on Australian-assembled CMPs and Ford conventional vehicles. I assume it was the same for Ford Canada (seems to be in your case), but Rob would be better informed about that than I am.

Yes, the engine number was really the only number until the first quarter of 1941 production, when chassis numbers were introduced. The manual indicates that the engine serials were into the 2G by this point. My reference for this is at home...I'll update this post tonight.

Mike: I see you reference 1G15318F as being November of 1941. Should that be 1940? Wouldn't a vehicle in November of 41 have a 2G prefix to the engine serial?
