Strange Case tang stamp. (mini copperlock)

Never realized this knife was like this, or if I did I didn’t realize how odd it is. My Mom’s mini copperlock that I got her about ~13 years ago. I borrowed it from her and carried it most of last week.

Any of my other single bade Case knives have the brand/year stamp on one side of the blade, model # on the other (Multi blade knives put it on different blades.)

This is the only one I’ve ever seen with it all nested together on one side.
