On the inside of the handle casting is: OPOG1520

I need a half-dozen handles. The windows have no manufacturer's name on them.

Thanks for posting! Your crank operator handle reminds me of the 39-232 Roto Folding Crank Handle. To determine if this is the right replacement, carefully compare the dimensions and design. You'll especially want to confirm that the diameter for the spline insert hole is 11/32".
