...I narrowed it down to three Remington 870 express and an older Wingmaster riot gun, or a Benelli Supernova....Anybody have any info on these older Wingmasters? They told me at the gunshop that they [Wingmaster 20" riot guns] once were police models from the 1970-1980 era. They look like they are in good condition on the outside but I don't know what to check for.
In 2006 Lee Lapin wrote, "In 1971 there was no internal difference that I am aware of between sporting Wingmasters and Wingmaster-marked Police and Riot guns. Differences were limited to barrel lengths. Police guns had 18" cylinder bore barrels, Riot guns had 20" cylinder bore barrels; and wood furniture. Police and Riot guns had 'corncob' or short police type fore-ends that were ribbed and plain oil-finished walnut stocks, while field guns had longer forearms and checkering. I have two Riot guns from that era and as far as I can tell they are 'just' Wingmasters with shorter factory barrels and plain walnut." Dfariswheel added, "Exactly. In the old days, factory 'riot' guns were just their commercial guns with a plain, oil finished stock and a shorter barrel. It's only in the last 10 to 15 years that Remington started to stamp their police shotguns with the POLICE mark, and that the guns started to have real differences in how they're built and equipped."
You could ask

The Express was introduced in 1987, the Express HD was introduced in 1996, and they have always been stamped Express, AFAIK. The standard $69.95 870, the 870 Wingmaster, and the 20" Wingmaster 870R Riot Grade guns were among the fifteen models of the 870 that Remington introduced in 1950. I think that 18" Wingmaster Police guns were introduced in 1953. It takes Remington about 5 hours longer of mostly hand labor at probably $40/hour to machine, polish, and finish a Wingmaster or Police model, than it takes to produce an Express. The 870 Wingmaster Police and Riot guns do not have the overly heavy 7-lb. trigger pull of the 1994 and later guns stamped 870 Police Magnum. (If I understand corrrectly, 18" and 20" guns stamped 870 Riot were discontinued in 1991. If I understand correctly, 18" and 20" guns stamped 870 Police Magnum began to be manufactured in 1994, although the 20" models were discontinued in 1995.) The bottom shotgun is a Remington 870 Wingmaster Riot gun made in 1987 that was bought from a retired sheriff's deputy for $350. It is not stamped Police or Riot, only "Wingmaster" and Magnum". It has blued steel, no engraving, a 20" barrel with rifle sights, and a walnut stock. I believe that by 1980, the 18" Wingmaster Police guns were actually stamped 870 Police. Corrections are welcome (and likely).
Good luck,
