anchor stamp

[runes]

I have an original 1861 Springfield with a small anchor stamped on the barrel flat just about even with the nipple. There is the number 185 just ahead and to the left .
Is this Naval or Marine issue?

runes,

The US Navy does indeed adopt an Anchor inspection stamp in 1866. This will usually be accompanied by the initials of the inspector assigned to inspect that type of firearm. (probably on the bottom of the barrel)
After the Civil War, as Ships came in for repair or refit or to be decommissioned, the Small Arms would be removed inspected for serviceability and cleaned. If the small arms were serviceable, they could be reissued to a Ships Armory (small arms locker) after receiving the Anchor acceptance stamp.
The Number 185 is most likely a "billet number". Such numbers were often issued to a crew member during his duty aboard that ship. While crew members may change or transfer, the arms were assigned to the ship.
I hope this helps

Thank you Blair for the information.
I have not taken the barrel off but will check that out.
