Looking for folding cranks to replace my existing Weather Shield cranks

Question

Weather Shield brand cranks for a bay window. I couldn't find any numbers. Installed in 1978.

Hey there. I think this might be the 39-014 Straight Arm Operator, but make sure the arm length matches what we show below. Let us know if anything differs. For a new crank handle see the 39-114L sold separately.
