100-300 USD
In 1950 Remington introduced fifteen versions of the Model 870 shotgun, in 12, 16 and 20 gauges.
Hey, I'm not sure about the worth, but I am also interested in the answer. I too just found a Remington 870 wingmaster 12 gauge made in 1951...
The W ahead of the serial number indicates that your Remington 870 wingmaster was made in 1972.
Winchester did not make a model 810 wingmaster shotgun.Remington made a model 870 Wingmaster shotgun,is this what you are asking about?
A lot less than a new 870 Wingmaster in any gauge. $300 if you are lucky. However, if it has the same year barrel and original wood and it is in 98% condition then it could be worth $750-900. With the box, paperwork and hang tag it could be a 1500 dollar gun. If it was a 12 gauge I would tell you to enjoy it and shoot it, but with the price of shells for a 16 gauge I would sell it and buy a 12 or 20 gauge. Since they have built more than 10 million 870s they have little collector value. I have a 1951 870 wingmaster in 12 gauge and I was stoked to learn that it was worth $300 and I paid $265 for it in 2008. I just hunt dove and quail with it and keep it clean and try not to scratch it up too much. An 870 is just a good working gun and should be used as such.
depending on age and condition, from between $250 and $450.
