I have windows with old worn out cranks - do you have replacements?

WINDOW REPLACEMENT PARTS .. Can You Help? .. Homeowners ask .. I have windows with old worn out cranks and very hard to operate. Some have stripped gears and just spin. I think these are CIRCA 1969 Windows - Pella or Marvin .. maybe Craftline? Can you help? .. What parts are needed for my old Crestline window hardware replacements - Old casement and awning style windows?

Here are some pictures of my Oldach window operators - do you have a replacement for this?
