Looking for window controller for Marvin casement window - Part no. 306-36

A home owner from Ithaca, NY says:
The controller seems to be about 4" wide and has a stamped number - 306-36. Another part says "Truth" but this name is not on the part of the controller I can see.

Do you carry a replacement part?

It's hard to tell what you have based on this picture, but look at our 39-036 and see if you think this is a possible match.
