Without seeing the actual gun lets say it is in NRA Excellent condition.If so I'd say its value would generally be in the 5 - 0 range. Box 700 Madison, NC 27025-0700You could also use the barrel date codes for month and year of manufacture.A vintage WM is first class condition for 5 is a great deal. Just home from the Pawn Shop and have suffered thru the glare of the Mrs. Looks like a 1979 gun from what I can tell off of the S#. Just has "mod" for the choke type on that side and rep on the other.
Box 700 Madison, NC 27025-0700You could also go with the barrel date codes as to date of manufacture. Wingmaster's like yours are still in demand, both as working guns and by some collector's if they are excellent condition, which you say yours is.Call Remington and give them the serial number, they will tell you when it was born, however keep in mind they due make errors. So, anyway, according to the above info, my PA barrel code and lack of serial # prefix, my Wingmaster has a mfg date of June 1953.Back up what they tell you with this information; DECODING REMINGTON SERIAL NUMBERSModel 870 LETTER PREFIX1950 TO APPROX 1968: NO SERIAL NUMBER PREFIX1968 TO PRESENT: LETTERS USED (IN SEQUENCE)S-68, T-74, V-78, W-84, X-90, A-91, B-94, C-97, D-01, AB-05Model 870 LETTER SUFFIX (DESIGNATES GAUGE)V 12 GA. What is the barrel code and the serial # letter prefix? However, the lettered barrel code is the best way to find the manufacture date, assuming the barrel is original. arrelcodes there are also apparently a lot of guns without the barrel codes. I have an inquiry into Remington, will report what they say. I have a vague memory of an article dealing with receiver cracks where the solution was to drill a small hole at the end of the crack. Dan I have heard of receiver cracks and issues with the LW 20s, but I have only ever seen two 12 gauges with cracks, and one of those had enlarged gas ports (didn't get to check the other one). As noted above, the serial number only identifies the model type (which might indicate a manufacture range, I should admit). The serial number has 5 digits and the W suffix, no prefix. They don't have a recorded date for that but believe it was in the 1970s.
