Casement Windows: Lock and Crank Arm

A home owner from USA says:

I was wondering if you can help me find replacement parts for my casement windows. I have pictures below of what we currently have. Please send a quote for one of each if you can. Thank you!

I believe your window could be from 1945. I do not believe these exact parts are still available due to its age, but I wonder if you can use the newer style Andersen window locks and operators. Start by looking at our 38-057 lock, 38-135 lock keeper, as well as our 39-094 operator and 39-286 handle.

I cannot guarantee that these will work, and they may in fact need some measure of handy work to fit, but they are the only options we have available.
