Hello, Jeff. Based on this picture, I recommend looking at our 39-013 and 39-014 operators. Make sure to confirm the dimensions match, as well. We also sell a handle that can work with these, our 39-114L.

Hello Paul,
The crank style looks to be more rounded in the edges.
Looking at 39-374 is more closer to the one I have.

Is there another model with the crank on the opposite side more closely resembling 39-374? Or does it matter?

Thank you for the help with this matter.

The rounded base doesn't affect the function of the window. The manufacturer just changed the style, that's all.
