870 Wingmaster 20 Gauge serial#

[rbdjr]

My dad says he has a 870 Wingmaster 20 gauge 2 3/4" no vent rib. looks like a 28 or 30" barrel,
it looks clean. He never used it much a few times a year, I am trying to find the year of the gun, I have the number off the receiver below the Remington @ Wingmaster inscribed on the receiver, 854016X, trying to find an approx worth of the gun in decent shape and maybe the year?

Definitely one built on the 12 gauge sized receiver (X suffix) before 1968. I would guess late 1966 or 1967.
Value would depend heavily on condition. Barrel is likely 28". $150 to $250 would be ball park.

And check the date code on the barrel....
