I lived in Tucson from early '78 to mid '86. Did a vast majority of all the shows(far fewer then) and was three time Prez of the Az Gun Collectors/Arizona Arms organization. Coming from Mn, I found far far more Rugers and overall, many more interesting items in AZ compared to Minnesota. Still have close Family in Tucson and some long time dear Friends. I stay in touch with the Desert........ 8) SBH SN 4564 was a Minnesota find, Rochester, MN, in 1975...........
