Jreb- that Proto clamp is a beaut. I have a different style old Proto that belonged to my grandfather. Very heavy duty like Williams.
Todays estate sale finds. -$22
About 30 people were waiting to get in the sale. I went hoping to get a Williams ratchet. A not well liked guy got the ratchet, and on it was the S-K 10mm socket from this set. I politely told the guy. He said "What size is it?". 10mm I told him. "Oh, that's a good size, I'm keeping it", he responded with a big grin. Cutthroat I tell you.

I'm going to remember that one next time.
This S-K is a partial set. The nice part is it's metric.
