I ran across this 70 series Colt today at a LGS, the pictures absolutely don't do it justice. Has a rear Bomar sight and a Bar Sto barrel. The gun is tight and has no visible signs of rust or wear. It could use a good cleaning of course. Anyway, I don't know much about these and have been unable to sift through the online marketplace since they are still apparently being manufactured. Seems as if a new one could be had for about the same price. Ammo for it seem relatively plentiful, about the same per round as say 357 magnum. Sorry about the picture quality, lighting conditions were not very good.
