3-1920's wood/cast iron furniture clamps -useful or rustic decorative - $100 (East Ventura)

My Uncle was born in the very late 1800's and he was a shop teacher in the 1920's.
I ended up with these stored for many years.
They could still be used in carpentry, but these days they are also used for retro creative rustic art projects.
With the cast iron, these are fairly heavy.
Ideas: Screw in hooks and use as a towel or other item holder or fix on the wall vertically or horizontally to clamp a stack of books or just display on a wall as decor, perhaps around or under photo or photos, or part of a collage.
$100 for all three.
Sizes: long ones = 52 1/2" (48"wood + 4 1/2" extension of metal) .
