3/29/19 - The G-prefix Olympic High Standard is considered to be the rarest of all the Olympic High Standard models, as only about 200 were made in the 1970s with a G-prefix serial number. This gun is stone mint and appears unfired. It is a complete, "as new in the box" set, that comes with a matching serial number box, manual and a warranty card. Chambered in .22 short, with a mint bore and grips. Gun can hold 10 rounds but the magazine is pinned at 5. A rare, impossible to upgrade set.
