Need replacement cranks

Question

I have the left swinging window shown on the pics and a right swinging window not shown, as it doesn't open. Can you help me find replacement parts for the crank mechanisms?

Hey there. This might be the 39-171 Dyad Operator. The opposite-handed version is the 39-172. Please compare. For a handle see the 39-114L sold separately.
