Operable hardware for a multi-sash awning windo

Question

The two photos show original (silver) and replacement (beige plastic) hardware for this window type. Replacements were made by others. I cannot find any markings on the hardware except some circles. The size is 4-1/2" x 2-1/8" plus the flanges. There are four sashes per window. Some of the existing hardware is broken- crank is diisengaging. Trying to find the right replacement hardware.

I'm not sure what to recommend. The white finish operator kind of looks like our 39-060, while the aluminum finish operator looks more like the 39-075. You will need to remove the operators from the window and carefully go over our measurements to confirm that these match up.
