1009 and 1011 are photos of 1970 crank handles and 1012/1013 are from 1993 windows with crank handle.Pella carries 3/8 inch inside crank handles.But that does not fit into 1970 windows .
It is amazing—rest of dimensions of handle are 100% same—outside dimensions.It is inside—old one were 7/16 inch—1/16 inch bigger than newer –from inside.
If you can find 7/16 inch from inside –that will be great.
