Center drive gearbox replacement

A home owner from Detroit says:
I'm looking for 1950s vintage center crank gear boxes for my louvered windows. The original manufacturer is Denison corporation. The gear drives two hex rods. Dimensions are 2 1/4 w and 1 inch tall. The socket wells are approximately 1 inch apart. The rods are 3/8" hex

Thank you Sarah

Thanks for contacting us, Sarah, and for your patience during this busy season. If all you need is the gear box, then I recommend our 39-076. This looks like a dead ringer for the part in your photo. Let me know what you think!
