Monday I found a 231D-20 Instruction book in the museum archives. It has a lot of pencil notations and on page 60 is a diagram of the Autotune mechanical parts with Collins Part Numbers.

I believe there is a very good chance the missing shafts on our 233D are the same. Here are the CPN's if someone could find a get a copy of these drawings, Don Grimm can machine them for us.

In fact attached is a scan of that page.
