Not certain I understand what you are asking. If your gun HAS a serial number, it should be stamped into the metal of the receiver (frame). In the US, serial numbers were not required by law on rifles and shotguns until 1968. Many older rifles and shotguns- especially .22 rifles, have never had a serial number, and they are perfectly legal,
Remington makes a variety of rifles and shotguns using various sizes of ammunition.

A number
A reference quantity.
Your question is to vague. Do you mean by projectile size, velocity, foot pounds of energy, popularity, cost, caliber.....
Smith and Wesson does not build rifles. The rifles they sell are made for them.
No they did not have rifles. They had muskets. They did not have rifles until the late 18th century.
I don’t understand the question
The absolute value IS the size of a quantity.
