This is a NOS Model T part that recently came in with some others we acquired.

Can you identify this part? The correct answer will include the name Ford gave this piece AND the years it was used?

Clutch finger. 1909-10? Never seen one like it. Being that this finger doesnt have the adjusting screw provision.

From the encyclopedia
DRIVE PLATE AND SHAFT
3321 (T-749)
Early 1909
Clutch fingers (T-732) had no adjustment screws. Bronze bushing (3327 (T-724) was 15/16 x 1-1/8 x 2”
1909-1913
Clutch fingers T-732B) now had adjustment screws T-756. A woodruff key (T-734) between the clutch shift sleeve and the drive plate shaft prevents the sleeve from turning but is loose enough to allow the shifting action.
1913-1915
The T-734 woodruff key (above) is eliminated.
1915-1925
T-775 disk added to tail shaft to reduce oil leaks.
1926-1927
3321B (T-749B) Redesigned to accommodate the wider brake drum. Clutch fingers (T-732C) and pins (T-735B) are new.

Frank is the closest.

T-732 is the clutch finger used on the first 2500 Model Ts only (that’s the hardest part of the question). After the first 2500 cars the finger was redesigned and the adjustment screw was added. The redesigned clutch finger was given the factory symbol number T-732-B. The first clutch finger was redesignated T-732-A.

Here is an example of a T732-B:

Although this particular example was produced after March 19, 1919 (on that date the Ford engineers called for the name “Ford” in script to be placed on the part). The early T-732-B typically looks like this:

While hard to see, this one had the symbol “M” sunk into the forging die, which was the trademark for Moore Drop Forge Company.

The next one is typical of late Model T production. It has the Ford script but not the factory number on it.

All these clutch fingers are NOS.

This last one was designated T-732-EXP. The EXP designates that it was a design for experimental production. It was a pressed steel design and had a very short production run. The problem with this design is evident in the last photo.

The pressed steel clutch fingers did not hold up in service.
