I recently picked up a Power Brute Super T-10. It has a cast-iron case and an aluminum midplate. The stamped-aluminum ID tag reads AS9-T10Y, which translates to a 2.88 first gear ratio, which is verified by the 4-groove input shaft. According to the date code, it appears to have been assembled in 1975. Overall, the unit is in excellent shape internally and shows very little wear.

What is a trans like this worth?
