After taking apart my Hard Hit Heart 12 Gauge bolt-action shotgun to hunt for the "K in a circle" mark I thought was present on the wood (I was
wrong...however, there was a circle with the letter "C" on the wood under the woodline near the trigger assembly, but that's actually not my
question), I found two baffling markings that I've neither ever seen on a Gewehr 98 OR on a Geha/Remo/Hard Hit Heart type shotgun. I SHOULD have noticed
these earlier, but at least I noticed them. The first marking is directly aft of the forward screw under the receiver. It's an oval with the letters
"JP" inside. Correct me if I'm wrong, but I'd always thought that was a proof for J.P. Sauer. While Sauer certainly COULD have made Gehas and
the like, it's highly unlikely that they'd have done so circa 1935-1936, which is when this gun was made. The second marking was just fore of the
magazine well, also on the underside of the receiver beneath the woodline. This marking was two small squares side by side, with both squares sharing a common
side (the line making up the left square's right side also makes up the right square's left side). Inside each square was the letter "J." Any
ideas?
