Need help with model of cranks and hinges

Question

The crank handles say SEMCO. I have three pairs of windows that were installed around 1995. I want to replace all the sash, window, and frame hardware for all six--three L and three R windows. The measurements I took all looked similar except for the stamped numbers. Unfortunately, the snow around my house kept me from getting all the numbers.

Thanks for posting. See our 39-031 and 39-032 Dual-Arm operators. These look awfully similar, but review the dimensions listed below and let me know if anything differs in any way. For covers and handles that work with these operators, see the 39-107 and 39-114L. If you need a new hinge, see if the 36-048 10" Hinge Set matches what you have. Let me know if you have any further questions about any of this hardware.
