Is this an under drive or something else?

It is a "Dual High" direct and underdrive.

As used in 28-29 AA trucks, in 1930 they went to the heavy duty 4-speed trans.

Yeah it's a real stump puller.

Can you explain what that means to a novice?

AR is a hobby term that relates to 1928 Model A vehicles that have the single brake system or early 1928 vehicles. When the early parts were discontinued, Ford put AR after their part number.

My observations from the picture:
Left hand brake lever - no separate emergency brake system – Beginning of Production (BOP) to 12/1928
Rear engine mounts 12/27 to 2/1930
Throttle linkage -June 1928 to Sept 1928
Single disc clutch -10/1928 on
Clutch access cover – 10/28 to 2/1929
Interesting clutch pedal to release arm rod
1929 hubcap on Rt. Front brake drum

On AA trucks changes could take place up to 6 months after the introduction of a part.
Anyone have any other observations?

Some have put them in a Model A backwards to make an overdrive.

Thanks. I did not know that. What I know about A and AA Fords I learned from my dad and brother who used to restore them back in the late 60 and early 70s. I am buying this thing specifically because I need the underdrive. Not sure what I am going to do with the rest of it.

As a (re)new(ed) novice to the hobby, might I suggest you NOT use the term 'AR' when describing a Model-A as the term is usually used incorrectly for what it applying to. Ford never used the term AR to describe a vehicle, ...and the ONLY time it was used was when a production assembly part (-not a component but an assembled part) was superseded by a revised part. For example an A-12345-A component might be revised by engineers and the identifying part number replaced by A-12345-AR followed by A-12345-B. While the 'AR' designations were for earlier production vehicles, only on rare circumstances did an A-*****-AR part ever get used on the assembly line. Therefore, the proper hobbists' terms are Early-28, Mid-28, Late-28, and Very Early-28. The VE-28 generally refers to A vehicles built in 1927, and the others are broken into monthly trimesters.


If your chassis has wire wheel hub caps, I would be interested in those.
