Window Cranks/Operators for Steel Casement windows

A home owner from Boston, MA says:

Hello,
My contractor threw out my original cranks and so i'm looking for replacements. I don't have any of the original parts but I do have these pictures. Can you help identify/source replacement cranks?

Hey, Paula. These are very old parts. I'm not sure if your exact operators can be acquired. Look at the list of hardware on the right side of this page. You may be able to get these to work, but I can't be sure.

Thanks Dave. I've finally getting around to trying to hunt these down again. Do you know how I might be able to determine if any of those will work? Maybe which measurements I should take of the window (as a reminder, i don't have the original operators)? Or is it possible to purchase them and then return them if they don't fit/work?

It's hard to say for sure what will work better, but maybe use the older style Fenestra, the 39-344 and the 39-358. I also suggest you might want to replace the sash track with the 39-504 just to be sure. If any of these parts don't work out you can always return them if you have to.
