I just bought a brass universal transmission, it’s on a TT driveshaft. I’m assuming it is TT only, or do they work on Ts?

Also does anyone know what this other transmission is?

Also does anyone know what this other transmission is?

Ford Model A

Thank you!

I imagine that Mark G is saying the other transmission is model A?
The 'brass' Universal looks like a TT two speed unit. It is missing the rear casting in the photo. Good units if you can get all the parts in good shape. Universal made both the two speed and three speed units, similar to the better known Rocky Mountain six speed. The three speed units were under-direct-overdrive in a progressive shift (TWO NEUTRALS to get stuck in!) (all kidding aside, they are easy to shift, and rarely stick in neutral, although it can be done so have added braking!)
The two speed units had a direct, and either an underdrive or an overdrive. The two speed one I had in the TT I had years ago had a small embossment on the center housing that was stamped as "overdrive", so look for that on yours.
The T car and TT truck units are not the same, nor easily interchangeable. The truck unit could be adapted to a car rear end, however, not a simple task.
I also had a TT truck three speed unit many years ago. The gears were good, but it had sat outside half apart for decades. I tried for several years to loosen it up and get it apart, but never did. I eventually took it to a swap meet with a moderate price on it it and some fellow said he wanted to try for awhile to get it apart. The three speed unit is a complicated gear within a gear sliding arrangement, and once frozen by even light rust is a tough bird to disassemble without destroying something. The two speed units are a basic transmission, and fairly easy to work on.

Here's the adv. for that Universal accessory transmission. For the TT, mounts to worm gear rear axle.
