Repairing or replacement from 1950?s Truscon steel casement hardware... the cranks don?t connect with the teeth on the arm?

Hello,
Take a look at our 39-001 window operator and see how the dimensions compare, as well as the wheel at the end of the arm that connects to the bottom of the window sash. Thank you!
