Good Day, Looking to replace window crank. The crank is for a bedroom window that opens to the right...4 inch base. One of the arms has the numbers 07900 stamped in it.

Hello,
This assembly looks a lot like our 39-388 and 39-387 operators. Take a look and see how the specifications compare to yours. Thanks for posting!
