I was given a 2.5 inch Python, blue, in mint condition. It is in the original box with the test fire target, a packet with an adjustment key, NRA membership form, and instruction pamphlet. The box says 357 magnum, 38 Special, Colt Blue. The serial number is 28XXX. The gun looks unused, and was probably only fired a few times considering what I know of the original owner. Does anyone know when this gun was manufactured and what its approximate worth is? I have done some searching on the internet, but there doesn't seem to be many 2.5 inch pythons around.
