There are a lot of possibilities. Can I see a few pictures of the handle in question? That will help us find a good replacement. Thanks!

Thank you for the additional images. Is this for an Andersen window? It looks like it, a little, plus Andersen operator handles usually have 3/8" splines. See our 39-267 and 39-286 and see if either of these can work. If not, can I see a few pictures of the operator itself?
