There are two Hayes markings on the choke reamers. One is simply his initials in larger letters. JPH. The other is his full name in small letters. The full name marking is the exact same marking/stamp that is on both Hayes Prototype Parkers. The 1910-1912 DH, in my collection, and the 1928 Trojan in the Remington Museum.
