Might have a case of a not thorough research at Ruger, Likely if they'd looked harder, may be seen that it went to NY, back to Ruger, then to Davidsons. The letters aren't perfect. Their info is at the mercy of whoever is looking up the info,Strangely enough, I've got a lettered GS-83 NYCPD 3" Speed Six with star produced in June 1988 that shipped to Davidson's in Dec 1988. No mention in letter of shipping to NY but star is stamped on frame. Previous owner was from Arizona near Davidsons.
I'd spend another $10 and include a cover letter asking them if the gun was returned to Ruger by NY and resold.
