Casement window crank

Question

I need 5 cranks for the window pictured. I do not know the manufacturer of the window, but I believe they are about 30 yrs old. Still in good shape.
I would appreciate any help.
Thanks

If you just need new crank handles, see our 39-114L. This fits on a spline that is 11/32" in diameter. If you need a new operator, I am afraid we are going to need to see the entire mechanism, including the link arm(s).
