Jaz,

The barrel flat on my H&H paradox is marked cordite 750 bullet MA nitroproof. The gun weighs 8.1 pounds. Also, I have a copy of the ledger from H&H that shows the gun was completed 2-28-10.The gun was sent back to H&H in 1912 to have an extra set of 32 inch barrels fitted. This set of barrels have 3 inch chambers and are magnum proofed. Are you sure your gun was built in 1910?

Regards,

Max
