Here is another older Security Six with dual ship dates. It was first sent to the LEAA in April 1974, and shipped again Oct 2009 with envelope containing fired case. Shipper has old label invoicing the gun to the Ruger "Dealer Book", I suppose that is an accounting thing for writing off the demo models. Also a hand-written note to return it to Newport per the enclosed listing (which is sadly no longer enclosed). No "S", "U", or funky "*" mark, but it qualifies as a Second because of the dual shipments.
