I need to replace this part so that my window will crank open. Built in the 1950s as you look at the window from the interior , it is on the right side.

I don't believe that we can supply this exact operator, but our 39-001 is similar and has been known to work on older windows like yours. Look over our photos and measurements and let me know what you think.
