I found a NIB Colt Diamondback .38 in a 2 1/2 with a very and I mean very light turn line. What a beauty. Serial number comes back to a 67 production. Price 750. No here's the kicker. On the left side of the barrel where it reads COLT DIAMONDBACK .38 Special somebody had .357 & added before the .38. It looks so close to factory I had to take many additional looks. Can't believe it. WHY!!!
