crank operator

Question

House built in 1978. Operator is very similar to 39-054. It appears that the dimensions for the fasteners that attach to the window frame are the same, but the arm extension is not. Arm extension is 3/4" wide and measures 2 13/16" +/- center to center. The offset is at the other end from the operator, the connection hole measures 9/16", and is not threaded, connects to a pin on the window hardware, and is secured with a clip.

I have also included a picture of the handle with what I believe to be the part that broke still attached.

The operator is marked:
Pat No D -198202 US
RH RD 1963 AN
The handle is marked:
??-11500-11 Pat Pend.

Hopefully you can supply me with the operators I need. I would purchase several RH and several LH in case they be needed in the future.

Thanks for any help

I think our 39-054 is a good choice. It's what I would go with, at least. There is travel in the gearing so it may be okay. Just double check to make sure all the other dimensions are good.
