it think you will find the long gun of the calvary at the little big horn were carbines, not rifles...
If you wish to supply the serial number,I can look up the date of manufacture for you.The serial numbers for the Springfield trapdoor rifles and carbines are in the general domain for people to find.
It may not have one. Serial numbers were not required by law on rifles and shotguns until 1968. A large percentage of .22 rifles made prior to 1968 did not have (or need) a serial number. And yes, they are perfectly legal.
It is located on the right side , same side it ejects, below the slide, and in front of the upper grip
None of the existing ORIGINAL guns have serial numbers.
No. Serial numbers were not required until 1968 on rifles. Most have a Sears model number that is mistaken for a serial number

This may sound strange, but if it never HAD a serial number, not a problem. Serial numbers were not required by law on rifles and shotguns until 1968. I have about 20 rifles made in the 1940s and 50s that do not have serial numbers. REMOVING a serial number is a serious crime, however.
It could be because sequential serial numbers would have allowed someone to collect a sample of rifles and then estimate the total number produced.
I don't know if all High Standard A-100 rifles (semi-auto, .22LR caliber) had serial numbers. Gun companies didn't have to use serial numbers until 1968, and a lot of inexpensive .22 rifles and shotguns didn't have any serial numbers back then.
