as described above. I don't have a disassembled sash. the pin is broken off on the opposite corner. I live in Groton, Massachusetts. I don't know the manufacturer. I thought I'd try to find one before killing hours trying to make a pin to attach to the broken key base. It is offset, adding to the difficulty. I've only seen straight pins on line.
I don't want to take apart the sash unless I have a replacement pin. I am in the process of replacing the felt on all storms in the 1981 built house.
Thanks, Vincent
