Can anyone tell me what year this cab is or how to tell the year?
25 and earlier
1924-1927 is my understanding. The very late ones may have an oval ignition switch mounting.
It doesn't have the trim on the vertical seams on the back, so I believe it's a '25.
I believe closed cabs came out in 1924 and were the same thru 1927. The trucks never switched to the Improved style fenders, cowl, firewall ect. They used the same fenders, firewall, front ends and front wheels, oval gas tank, steering columns (the bottom bracket of the steering column is different) and the hand brank is also different due to the different thickness of the frame. These parts were the same as the cars.
I believe Layden and Derrick are right. There were some minor differences in the years. The switch was changed sometime in 26 or 27 Im not sure when. As to the trim on the back, maybe someone else sill chime in on it.
From the Encyclopedia:
APR 9 1925
Acc. 235, General Letters, Ford Archives
Closed cab for trucks announced.
APR 29 1925
Ford Factory letter
A closed cab is the latest equipment offered by the Ford Motor Company for the Ford ton truck. The new cab, which is all-steel, affords protection for the driver and is adaptable for use with standard Ford truck bodies, both the express and the stake types.
Doors of the cab are exceptionally wide and the plate glass windows in the doors may be lowered. The upper portion of the windshield swings either in or out so as to suit ventilation requirements. The seat accommodates three persons comfortably and there are special springs in both the seat and back cushions. Panels in the back of the cab may be easily removed to permit access to the truck body.
A combined priming and carburetor adjusting rod is now standard on all Ford closed cars, and is being furnished without extra cost. Where formerly the driver primed from the instrument board and adjusted the carburetor from the dash beneath, both operations may now be performed from the same accessory on the instrument board.
Ford owners who desire to "dress up" their cars with nickel-plated radiator shells and head lamp doors may now secure these accessories from Ford dealers. This equipment is being supplied by the Ford Motor Company to authorized dealers throughout the country.
My '25 had fender welt in the vertical back seams (remnants thereof). I don't recall any different configuration on any of the 26 and 27 models I have seen. My impression has always been that the 24 thru 27 closed cabs were identical except for the later style switch plate on the 27 dash.
I've always thought that the '24 & '25's were the C Cabs and the '26 & '27's were the square cabs. These were the only one's made by Ford. I have what I consider an early '26 that has the brackets for the side lights and the large square instrument panel and 30x3.5 front tires. It has no serial number on the frame and the engine is not original. My '27 is late by the serial number on the block and frame and has no side light brackets and the small nickle plated instrument panel. It has 4.50x21 front tires.
Check out the encyclopedia for 25, 26 and 27 at:
C cabs and enclosed cabs were made in 25 and some C cabs on into 27.
I stand corrected. It appears, from the info in the encyclopedia that the closed cab started in 1925. If you use the April date in the letters to the dealers, it also appears to be in the last half of the model year. ??? I learn something new all the time ...
When you say "vertical seams" do you mean all verticals on the back of the cab, or just around the window or where?
With a cowl vent, my guess would be 1926 27
Tom, The rear cab panels (2) are removable as you have discovered on your cab. The vertical seams are where the panels fit into the rear of the cab body corners. When I first disassembled my cab I found remnants of what looked like body or fender welting in those seams (both horizontal and vertical). When I reassembled my cab I discovered why it was there, as the seams leaked water and squeaked badly at those junctions. The rear window glass was installed with a rubber gasket.
All 25-27 Ford closed cab bodies had cowl vents.
Here's a picture of the trim on the vertical seam of the back panel on my August 1926 closed-cab TT.
I don't know when the trim was added, but mine is pretty late in the '26 model year. My extra cab has it also.
The Enclosed Cab at the beginning of this thread is an early one built between April 1925 and August 1925. You can tell by the high mounts for holding the windshield open. These high mounts were discontinued for 1925 models then lowered for the 1926 models.
Derek you have a 1927 model enclosed Cab. All cabs for the 1927 model year had these reinforcements added to them.
