Krag Serial Help

[butlersrangers]

U.S. Model 1898 rifle, #122033, and rifle, #122633, were both assembled at Springfield Armory, around August, 1898.

Neither serial number appears in the Springfield Research Services data - (SRS list of Krag serial numbers found in official documents).

Numbers close to your mentioned serial numbers were issued to the 3rd Kentucky Vol. Inf. in 1898 and 1899.
Note - A serial # being 'close' to known rifles, but, not recorded, means nothing.
It actually pretty much guarantees your Krag had a different fate or history.
