Window crank mechanism

A home owner from Massachusetts says:
These windows are quite large approx. 3'x 5'? All aluminum I think and have 4 window panes all incased with aluminum. I cannot find a name brand anywhere on it.

Your operator resembles our Center Gear Operator,  39-076. It is the only part available for this older awning window. We believe it was originally made by Stanley.
