At the 1966 NRA Convention & Exhibits in Chicago, Illinois, a select group of Writers and Editors were invited to a private meeting for the introduction of the Ruger No.1.
Either 3 or 4 Prototype rifles were shown to the attendees. Below is a copy of the Invitation sent, courtesy of my friend Don Findley. Don is Historian for the Ruger Owners & Collectors Society, Inc.(www.rugersociety.com) and has an extensive collection of Ruger papers.
