Below is an original tag off a Model T rear end housing. It says "PERFECTO 2 speed axle Ruxtell sales and manufacturing Co. Berkeley, CA MFD. by Hall-Scott Motor Car Co." It has patent dates of 7-15-19 and 1-27-20. So were the first 2-speed rear ends labeled "Hall-Scott" and later "Ruxtell"? Where does "Perfecto" fit in? What years should have what labels on the housings? (Had to get you guys off MMO, 6vt vs 12vt, oil viscosity, Kevlar, disk brakes and distributors.)

I will try again.
Perfecto was the first version of the Ruckstell. None of the parts except the ball bearing are interchangeable.
They were made for about 2 years nearest I can figure. Ruckstell acquired the rights to produce them in 20 or 21. Glen Chaffin is up the history, so he may want to comment. I've restored a number of them and they are difficult to restore, but are a joy to drive.
