Old window crank casement broken

A handy person from CT says:
1950's house previous owner obviously had trouble opening crank window and broke the casement. I don't see any name or numbers to any of the parts. The broken casement is one of 4. The only identification that seems unique about this crank model is there is one screw (see white bump - painted over screw) noticed outside casement opposite the the crank (see photo). Currently the broken casement window has been sealed shut and is not is use. Can it be the casement and parts be replaced or is it even worth it? Thank you.

Thanks for contacting us. Unfortunately, this operator is no longer made and I'm not sure there is any ideal substitute for it. You may be able to adapt our 39-094 and 39-095 Andersen operator and track kits, but they won't be an exact fit and would likely require you to retrofit the sill to accommodate them. Even then, I cannot guarantee that they will work. Please carefully go over this hardware and let me know what you think.
