1939 Allis B Single Bottom 2 Way Plow

Maybe this will help, assuming your plow is the AC version. There were aftermarket versions of the 2-way pick-up plows for the B, such as WIARD Plow Company which are quite different in mounting and lifting. Click on the thumbnail to bring a full sized diagram.

Here's a view of all the parts with the single exception of the piece that mounts just under the PTO in the tractor center. I leave that in place all the time. This is for the WIARDS that I have. I don't have a "C looking" cast piece but there could be variations out there. I have never run across anyone that had anything other than the standard AC plows. Perhaps it has something to do with mine being a wartime '42B. Dad got the plows new with the tractor.

And here's a view of the plow hookup. Perhaps the U-shaped pieces shown are similar to yours.

No, I don't have a manual for mine. I have never seen one either. I haven't used them in about 30 years but fortunately I remembered how they hooked up when I took the pictures about three years ago. I have some more closeup pictures if you think these are the ones you have. I'd be glad to help in any way I can.
