Today I bought a 20 gauge Remington 870 Wingmaster. I don't know much about shotguns, but it looks like it is in good condition, but not very new. The serial number is 1911xxx The last x is really an x, and the first two are for the last two serial numbers. Would appreciate any information about this gun as to age and value. I paid $100.00 for it, and the guy I got it from said he bought it used 8 years ago.
