Purchased this T today and still trying to figure it out. I am thinking `25 TT but not sure.. Also picked up this additional frame w/ Quarter elliptical suspension for the wheels" T " I believe.
Yes, it's T, not TT. What there is of it looks like 24-25. You can date the engine by the serial number stamped above the water inlet on the side of the engine. I don't know what the wagon is.
The body is remnants of a C-Cab, but the rest is just a T chassis. The rear axle is a T. A TT has a much heavier rear axle. The last photo is of a homemade trailer. The wheels look T, but the frame is from something much heavier. I hope the C-Cab doors are in your pile of goodies.
