I have a hardball gun made up on a 1927 Argentineicon frame. I paid an army armorer to build it for me in the early 1970's. Nearly all parts but the receiver are NM. I suspect there will be a time in the future when an owner of this pistol will
try to figure it's history. There were lot of competent gunsmiths and military armorers doing such work in the 1970's.
