1980 model 870 Wingmaster.
The nice lady at Remington confirmed that this was a "Police" model when it left the factory.
It had only been fired once or twice, when I got it. The underside of the carrier didn't even have a mark on it, from being loaded!
The owner's widow put it up for sale.
I found this at a gunshow.
20" cyl. choke.
$210.00 OTD!!!!!!!(Seek and ye shall find!)
