I have an original Spencer 1865 carbine, serial number 14237, that was given to me by my grandfather. All I know of it is that it was purchased in Texas and Springfield Research lists numbers 14238 and 14147 as issued to Tonkawa Scouts at Fort Griffin, Texas in 1873 (there doesn't appear to be any 1865's listed by SRS between those numbers). The carbine appears to be all-original with the exception of a somewhat crude blade rear sight (I did find an original replacement a couple of years ago but never mounted it).
Does anyone know of another source for researching Spencer serial numbers, or have an idea where I can find information on the Tonkawa scouts?
Thanks,
Trey
