I bought this Wingmaster 870 a few years ago out of the blue for $500 but still haven't been able to figure out what it is specifically.
It has a 20"bbl, +3 mag extension and LEO folding stock. 2 3/4" shells only. The barrel code is either "OU" or "UO" -- can't quite tell. I think the date is either 1971 or 1977.
The previous owner claimed it was a police-trade in that had spent most of it's life riding around in a cruiser. The left-side of the receiver is engraved with "State Highway Patrol -- Ohio" and has a good amount of finish wear to support the story.
There's a few things that concern me -- first is that the shotgun has sights from an early Rem 700 rifle instead of a bead sight. I happened to ask a collector about this and was told it may have been done for a contract, but I haven't found many other 870's like it. The second thing is that it looks to have been re-parked, but I can't figure if it was originally blued or not since I haven't been able to find another LEO folder that was parkerized. The bolt is also parkerized.
Is this shotgun collectable? What would the approximate value of it be?
My apologies for the crude photos -- had to use my phone
