Need wooden Window cranks

A home owner from Benton, AR says:
I need the cranks for the window. The house was built in 1974. This is a wood window. The shaft is 3/4" tall. Width is 5/16", not including the teeth. No markings were found on the window.

Thank you for posting. These look like they could be Pella windows. Check out our 39-176 & 39-175 and see if either of these could be used as replacements for your hardware.
