I am looking for the "Expansible Bracelet Clasp" for my 1943/44 Bulova Minute Man watch.
The clasp is/was used on a "basket weave" yellow gold mesh band. I have included 3 pictures for the clasp along with the patent for it.
Somehow the "pawl element" (#46) which includes the integral "finger operated member" (#56) and it's "curled" end (#48) managed to loosen and fall free. It's all one piece.
