Remington 1903 Unusual Barrel Stamping
I recently got my first 1903. Upon inspection of the rifle, I noted a stamping on the right side of the barrel just behind the front sight. The stamping is sharply imprinted - "30:06". I have spent several hours researching and can find no evidence of this being done. I suspect that the rifle might be a foreign country return, that country using rifles with several calibers of ammo. The serial number of my rifle is 614xxxx. Any help or information will be appreciated.
