I have recently acquired a Watson transmission mfd by the Brown-Lipe Gear Division of Spicer Manufacturing.

It sez its a model 2021 (i think).

Here is a picture of the whole thing - note the small size next to a common screwdriver.
Small Overdirve - click me - Direct/Over speeds only

Does anyone have any manuals or information they can give me regarding this jewel? Its going into my 59 1 ton and it looks to be like a .75 overdrive unsychrnoized. So any suggestions would be helpful regarding installation, maintenance, or driving.

I haven't found any information about it on the net in my searches.

Thanks.

(Btw, you haven't seen me posting lately because the 59 is doing well and most of my time is spent on my 47 cj2a 'heep')
