I need a replacement window crank and multiple handles because the treading stripped on some cases and handles were lost. The crank is made in U.S.A , U.S. PAT .4505601, PAT. Canada 1986, U.K. PAT .2135397. I think the company might be "TRUTH". Do you know where to find this crank?

I think we actually carry a match. Look at our 39-316 to start out and carefully look over our photos and information. Let me know if you agree that this matches up!
