"Poly-Tex Pittsburgh, Penn." no numbers or other markings right and left latches are the same, just turned around.
Thanks.

Hello!
Your top tilt latch looks like our 26-120 and 26-121, but made with custom screw holes. You might be able to use ours and drill out that extra hole. Carefully compare your dimensions to ours and see what you think.
