Hello there. Can you send photos of the hardware in question? We need to see the operators from a bird's eye perspective, with the arm(s) that move the window and the gear body in full view. We'll do our best to help from there.

That's a huge help, thanks! Based on these photos, I would recommend our 39-388 and 39-387. These are Wright operators, just a little more modern compared to your older hardware. As long as the arm sizes match up they should work just as well despite the differences in style.

I'll measure out the arms to see if they fit. BUT also need the stationary receiving tracks that attach to window sill and bottom of window. See pics / pencil

Sure, that'd be the hinge. You'll need an all new hinge assembly. See our 36-048 for my recommendation. Note that this has a base track of 10", so make sure that this is the same before you buy anything. Also note that you need to replace the top and bottom at the same time. You never want to mix old and new hinges.
