Thanks for posting, and for the clear picture! I recognize this operator. Unfortunately, it is no longer available. Our 39-091 might work, but I have personally never tried it. The base appears similar to our 39-248, and that should work if that's all you need.

Thank's Dave for the fast response, the base plate looks like a match and should work, however i need to know the dimension of the arm on the 39-091/ 39-092 operators. there other dimensions are workable but need to know the 3 1/4 dimension on my photo. thank you again any help here is great.

Thank you for your patience in this matter. It looks like the arm length is approximately 2-13/16". What do you think? Is this something you can get to work?
