This is a pair of Japanese Berloque 2mm pinfire cufflinks. These are like J3a in bob Urso’s book, except these are marked JAPAN, one on the right side, the other on the left side, and these vent through to the muzzle, not out the bottom. Quoting from Bob Urso’s book, and used with permission: J3a – Little Atom, square Butt, OAL 1 3/4″, nickel plated brass, pressed checkered grips. This square butt model of the Little Atom is unmarked, but was, like the round butt model, packaged and marketed as a Little Atom.” Excellent near mint condition showing only the slightest signs of ever having been fired. Price: $150.00.
