Hello, i found these today. The 2 at top I am calling some type of clamp. The 2 show the min. & max. opening width. Overall length at the top is 7-1/4" with an opening of 6-1/4", the next one is 5-1/2" overall, and is open to 4-1/2". Former owner was a woodworker, clock maker, tinkerer. The pliers at bottom are 6-7/8" long, bending or wire forming pliers? I was told possibly for manual typewriter repair? Thanks, Lou
