Taking a shot in the dark here. Looking at a nice used shotgun at a local gun shop. The tag says it's a Remington 870 20 ga "skeet" with 25.5 in barrel. But it has very a nicely grained walnut stock with nice checkering/scroll work and checkered forearm (and recoil pad). Appears to have been well taken care of. I asked the guy if it was a Wingmaster (or whatever), and he said it was just an 870 as far as he knew. Can't find anything exactly like it in my "Standard Catalog of Firearms" except the Model 870 Field Wingmaster, which is as closed as I can get. He wants $350 (down from $400) for the gun. Have to admit I'm not exactly an expert when it comes to shotguns, but this one seems too be a nice gun for the price. Any ideas what we may have here?
