Here is my 4567. I purchased it from a dealer in Baton Rouge, Louisiana in 1997. The dealer had four of them. Three of the four had matte blue finished slides and one had a polished blue slide. I took the polished blued one. These 4 have spur hammers with night sights and are Lew Horton Specials. All are marked Performance Center Classic Series.Serial number on mine is TFP09xx
