FAT cab 12 frame serial no location.
 

As the title suggests, I am looking for the likely locations of the cab 12 Ford artillery tractor frame number. I had no luck in the likely places of under the left door area, nor by the right rear spring hangers. Any suggestions?

Hi Rob
On my Chevrolet CGT cab 12's. The body number is on the vertical face in the driversside when you open the door. The chassis number and engine number is on plate on the engine cover next to the driver.
But this is on a Chevy not a Ford so it might not be a help

This body has a body number in the location you describe, and the serial plate is missing. The museum is being offered a set of plates that may be original to this truck, but I am trying to determine that the plates offered are in fact for this particular vehicle.

I will look at the engine serial number to compare, but of course engines get changed after 70 years. But generally frames do not, which is why I am looking for the frame serial (if it exists). I have observed serial numbers under the door on Ford Cab11 trucks, and forward of the right rear spring hanger on Ford cab 13s. But I did not find numbers in either location on this cab 12.

Chassis number
 

I can only speak about the Ford CMPs here but as you probably know the engine number is also the chassis number. Ours were usually but not always stamped on the top right hand chassis rail adjacent to the engine mount, sometimes on the vertical face nearby. The other place to try is the top of the bell housing on the gearbox assuming it is the original.

The engine number is also the transmission number so if your data plate number is on either of these then you're there

Thanks for the tip on the number on top of the frame rail. I had only seen that location on the pilot vehicles up to this point. I'll have to bring my flashlight to the main museum building next week and have a look.
