Anyone recognize these C clamps?

[WWShop]

Bought these at a garage sale for $10 but can't find any information on them. They are really smooth and work really well but a google search turned up zero for me at least. They appear to be aluminum. Any help?

Adjustable clamp co.. Same as Pony and Jorgensen for the most part.

I have a few like that, but they are not the *********** version that you have.

"Adjustables" are fairly common here.

Likely they are forged iron...a magnet will rule out aluminum.

Those are pretty sweet. I took a pic of this one in my local welding supply shop today. As Trump would say "it's huuuuuge"

They look very similar to a Paulcall clamp.
