pair large antique iron farm worktable clamps w/cast handwheels

Rare pair of large and heavy old iron clamps from an old farm estate. These clamps are clamping tools and materials to work tables in the old farm kitchen and to workbenches in the workshop. These clamps are rather rare and unusual in that they have teeth (small bumps) on the lower jaw to bite into the wood of the table to keep the clamps from sliding off.

They can be adjusted 2.24" down to 1" between the clamp jaws. The cast iron hand wheels measure 2 3/8" across.

These have a patina of age.
