You should be able to get a manual by calling Remington. catalogue the Model 11A got a checkered pistol grip and forearm. It remained like that in the 1923 Remington Arms Co., Inc. catalogue of 1918-19 the Model 11A had gotten a full pistol grip but was still plain without checkering. 11A had a plain walnut half-pistol grip stock and forearm without checkering. Up thru at least the 1913-14 Remington Arms - Union Metallic Cartridge Co. I've always kind of figured this making the Model 11 and The Sportsman receivers the same was a DuPont efficiency expert cost cutting measure. They also began putting the "The Sportsman" or "Model 11" on the bolts about that time, and dropped the seperate serial number sequence for "The Sportsman" numbering them right along with the Model 11s. 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). Circa 1937, they reduced the roll-stamping on the sides of "The Sportsman" to one bird on each side, and started putting that roll-stamp on the Model 11s as well. I have a 16 GA Sportsman with serial number 1592276 and barrel date code of LUU(1949). Controlling interest in Remington was acquired in 1934. When the three-shot version, "The Sportsman" was introduced in 1930 in 20-gauge and 1931 in 16- and 12-gauges they had a three-bird roll-stamp on each side of the receiver, and their own serial number sequence, while the five-shot Model 11 was still plain. The 16-gauge wasn't introduced until 1931, and all have the cross-bolt safety. The model number represents the specific model of the shotgun, while the serial number is unique to each individual shotgun. began producing the Model 11 in 20- and 16-gauge as well. Is the model number the same as the serial number on a Remington shotgun No, the model number and serial number are different. At the same time The Sportsman was introduced Remington Arms Co., Inc. The safety was changed from the lever inside the trigger guard to the cross-bolt behind the trigger in the late 1920s. The early 16-gauge The Sportsman were in the 200000 serial number range, and the 12-gauges were in the 500000 serial number range.
The Company name was changed to Remington Arms Co., Inc. 11 around 1911 in the Remington Arms - Union Metallic Cartridge Co. 11A was the basic grade from the beginning of use of the term Model No.
