Welded Knight Casement Window Crank

A quick learner from Southampton, PA 18966 says:
I need to replace a welded knight casement window crank.
There is a sticker on the frame that says NBP-K-007.
The gears don't mesh any longer.

I'm not familiar with that name. Could you remove the crank operator from the window and show us a picture of it by itself? That will help us find a good match.

Here are some pics of the crank.
I believe it's a Roto.
Thanks for your help.
