This firearm, which Smith & Wesson refered to as the Highway Patrolman, was made sometime betyween 1972 & 1977. The exact date is difficult to pin down, because S & W undoubtability (this is speculation on my part) stamped s/n's on frames in batches well in advance of using them.
Value is difficult to est. without some idea of the condition of the firearm. There are also a couple of variations of this gun that can also affect the value. The Blue Book of Gun Values gives a range, for an unmodified standard grade gun, of from $395, for a gun that is as it left the factory, down to $195 for one with only about 60% of its original finish left. These figures are retail and assume that the gun is in good working condition.
