I've been searching for a nice (not NIB safe queen!!) Model 15 and 18 for quite some time. Found the 18-3 on this forum then went on a short vacation and stopped at a new gunshop 250 miles from home and BINGO-scored the 15-3! ($380 plus tax and instant check-a great deal IMO)
Model 15-3 Combat Masterpiece .38 Special circa 1971- 98% with original numbered Magna grips. I added the mid 1970's target stocks.
Model 18-3 Combat Masterpiece .22 LR circa 1974 - almost 99% TT, TH, came with the gorgeous mid 1980's target stocks. (This one was $$)
