Alcoa Window Parts

A home owner from Naples, FL says:
Hi all,

My condo was built in '81. I believe the original windows are Alcoa windows.

I'm looking for replacement parts, preferably in white:
- Handle and crank
- Plastic cover at top
- Lock

See pictures attached.
Thanks for your help!

Thank you for posting. I'm not sure exactly what your operator and lock are, since we can only see their bases. There is more to them inside the window; that is, the actual arms that do all the work. That said, see our 39-013 operator and 38-036 lock. You should remove your hardware from the window and compare them to these two parts to confirm that they match.

I'm afraid we will not be able to replace that plastic cover. I'm not quite sure what it is, to be honest. What is its function?
