Replacement Hope's window operator

A handy person from Albuquerque says:
The only markings are "HOPES" and "Jamestown NY" on the top and "L.H." on the underside. There are no other numbers or letters anywhere.

This is a very old operator. I don't know if we'll have an exact match, but our 39-354 may work as a replacement. I think this might be a modern version of your old part. See what you think.
