Mossberg 500 is a series of shotguns manufactured by O.F. Mossberg & Sons.The 500 series comprises widely varying models of hammerless, pump action repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, and "furniture" (stock and forearm) materials. Model numbers included in the 500 series are the 500, 505, 510, 535, and 590.
Your Montgomery Wards Model 550ABD was made by the firm Mossberg and Sons.The Mossberg model 500 and your shotgun are one and the same.
I THINK that was is a Mossberg. The WesternField model m550ABD Is in fact a Mossberg Model 500. I am a proud owner of one, which every member of my family has hunted with. This gun will accept mossberg barrels, and retains amazing accuracy and reliability.
One was purchased new in 1974.
This is the same gun as a Mossberg 500. You can try a google search or go to the gun parts Co. online for a diagram of an exploded view. Mossberg should have one as well.
Revalation was a brand name of the Western Auto Hardware Company. Many guns were manufactured for Western Auto by Mossberg, Marlin, and perhaps others that had the Revalation name. They have not been sold for years now and any in stock would be used guns.
Pawn shops offer inexpensive previously owned items, often those items include guns. When purchasing a fire arm you would have to follow state specific guidelines.
You need to remove the recoil pad. Once the pad is removed the stock is hollow. You need a long flathead screwdriver to remove the one bolt holding the stock on. Shine a flashlight into the stock and you'll see the bolt easily.
There is no difference. A 500 is a basic Mossy 500 receiver shotgun. Unless the gauge is stated, it's assumed it's a 12. The 500A is simply stating it as a "12 gauge" 500 in its name. The Mossy 500A is a 12 gauge model 500, the 500B is a 16 gauge model 500, the 500C is a 20 gauge etc. There was no 28 gauge so there is no 500D, contrary to many sources, so the next one was the .410 called the 500E. A 12 gauge model 500 and a 500A are the same gun.
The Westerm Field 550 looks like a Mossberg 500, so I would start there looking for a plug. A good gun shop might have one, a gunsmith could make you one, or gunpartscorp.com may have one on the shelf.
There are a few on gunbroker, in fact there is one on there now. Mossberg originally designed the bullpup for law enforcement / security use. It found quite a few fans in the civilian market though. Mossberg desiged it, I'm not sure if it was contracted out though. They have the ability to make all of the synthetic stocks for their regular lines of shotguns. it could have been a company like ramline which is known for it's stocks and innovative concoctions.
I will buy one (395K 12 guage) top price as i have one from my father that is broken, even parts would be great, especially stock. LarryAndy@aol.com
