For the "checking" on gun stocks?

They look too old for stamped "checkering."  Stamps like these, however, were used for back grounds in bas relief wood carving.  You'd carve the image, field the surrounding area down, and then stamp that area.

I think I found ones similar in leather working tools. Ebay #220767345481

They also look like the faces on bush hammers used for smoothing stone.  They could be chisel type versions of that stone mason's tool.

The bigger ones look like the feet, placed in the end of the extension tube on a Port-a-Power hydraulic press.  To keep the feet from kicking out under pressure.

I have also seen early car jacks that had removable pads similar to the larger two?

I think it could make a good texturing stamp for leather work...

 They look like shrinking dies for sheet metal work.
