Hi: I've attached 2 PIX of the aluminum handles that operate my 1960-era casements mfd by Curtis Woodwork, an 1866 window mfr, now defunct (originally based in Clinton, IA). Do you have something that would either be identical or similar to replace my 3-4 windows now needing these replaced? The windows are, otherwise, great, even if energy-inefficient. The approx. 16" long arms have a hinge in them and are attached to the wood frame of the swing-out window. They pass thru a small "tunnel" fixture attached to the house frame and from there, pass thru a small hole in the removal screens.
Thank you very Much--Alan
