Thank you for your email. I've attached several pictures of the jalousie crank. The before and after pictures of the assembly with and without the handle. I've also included pictures of the universal T crank window handle that I bought to replace the broken one . By looking at the pictures would you be able to tell if the replacement is the correct one? After looking at the crank assembly I didn't think it would work. The original crank handle doesn't have a screw, it is riveted in place.
Thank you for your help
