Casement to folding crank replacement options

These windows were done in a hotel remodel early 2000s but the owner is unsure of the window brand. They are looking to replace this crank style with a folding crank option if possible (something like 39-375). Any idea what product would work for that? I realize I'm not providing much to help.
Thanks.

Thank you! I'll share with the hotel owner to see if this may work for them.
