The model 6 was made from 1901 to 1928 and that's a fairly late serial no, they made approximately 450,000 before the improved model in 1929 started. Since it's a later one it should be date coded on the barrel left side in front of receiver a diagram and chart can be found on the Remington Society of America's (Collector Site) here: http://remingtonsociety.com/rsa/questions/barrelcodes
Remington firearms can be dated- but NOT from the serial number. There is a 2 or 3 LETTER code stamped on the barrel, left side, about a quarter inch from the receiver. Go to the website for the Remington Collectors Association for the chart to translate letters to month and year.
The Remington model 121 is the improved model 12 and is still considered one of the finest 22 pump rifles made. They were made in 6 general models including those chambered for the .22 Remington Special Cartridge (.22 W.R.F) from 1936 to 1956 in quantity of approximately 200,000. In better condition they are considered quite collectible.
The Remington model 6 rifle in .22 caliber is a rifle made from 1901 to 1933 resembling the rolling block rifle. There were three grades offered, the first from 1901 to 1903 is the original model 6.

They come in .22 short, .22 long, .22 long rifle, and .32R short. Some of them were made Remington- Union Metalic Cartridge company. Some versions have sights on the grip that folds upward, while other variations have a fixed sight about half of the barrel down. the fixed sight version has a U rear sight and a standard blade foresight.
