Window operator from Florida home built in 1958.

Take a look at our 39-084 operator, which was used by Crown. See if it matches up to yours. To be honest, yours probably isn't made anymore, based on its design. They don't really make operators this heavy duty anymore. I think as long as the dimensions match up to our 39-084 it'd work well as a replacement. If they differ, however, let me know and we can try to find something better.
