Replacement of folding Andersen window cranks for casement windows

I'm afraid I don't recognize this part. It looks like it might be part of a greater assembly. Would it be possible to see the whole thing in undamaged condition? That might give me a better idea of what you're working with and whether this is something we can supply.

Thank you! That's a huge help. That appears to be a match for our 39-301. The base is unfortunately not sold separately, so you will need to replace the entire handle.
