Hi I am new here I have a couple of remington model 11 shotguns can anyone help with the dates thanks for your time. Combined 12-gauge 'Model 11' and 'The Sportsman' serial numbers reached 499,999 on August 1, 1943. By mydogchomp, 11 years ago on Remington. I love the old Remingtons humpbacks, regardless whether they are pre-model 11s or are Model 11s. From then on the 'Model 11' and 'The Sportsman' were serial numbered together, continuing the Model 11 sequences. Why not post a few pictures of your gun showing all these features? I'd sure like to see it. Manufacture of the Model 11 ceased in 1948. In fact, the real early Remington autoloaders that I've seen have often been confused with early Browning A-5's because they did not say Remington on the barrel. The barrels of all the real early ones that I've seen have been plain to the point that nobody has been able to tell if they were actually original to the gun, or were added to the gun later, because none identified Remington as the manufacturer. So, if I am correct that the Sportsman started with a new set of serial numbers, these two combined would be 3,166,918. And I have a 16 GA Model 11 with serial number 1574642 and a barrel date code of XSS(1947). It didn't become the Model 11 until 1911.) All of the very early guns like this that I've seen do not have the flying duck and flying pheasant rollmarks on the receiver like the later Model 11's have, and they do not have Model 11 rollmarked onto the breechbolt like the later Model 11's do. I have a 16 GA Sportsman with serial number 1592276 and barrel date code of LUU(1949). (From 1905 until 1911 the Browning patent automatic shotgun that Remington made was simply called the Remington Autoloading Shotgun. I don't claim to be an expert, but all of the Remington "Model 11" 12 guage shotguns that I've ever seen or heard of that have six digit serial numbers located on the bottom of the receiver have been very early guns I think some of them and maybe all of them that I've seen were made even before the gun was called the Model 11.
