I received a Colt 38 D.A. 6" barrel from my dad, who got it from a retired Police Chief many, many years ago. Based on what I've read, I believe it must only use the 38 Long Colt ammo (probably hasn't been fired in over 50 years). Since the cylinder rotates counter-clockwise, it must be one of the early models. The serial number 96 510 is on two lines - could it be an 1898 New Army model? I have attached a photo to see if you could tell me what it might be worth and any other pertinent info. Thank you.
