We have two 870 wingmasters, both are 20 ga.
#1 The oldest one was made between 68 and 73 and is in great condition.
#2 The newer one was made between 74 and 77, it has some blueing worn off from being carried and a few light scrathches. It has the original box still with it.
We were just wonder what they are worth, we are NOT selling them, just curious
