Any red flags on this 1903?

[RCS]

Here are some examples of a USMC shovel cover identified as USMC and with the ship name. I would think that the USMC detachment on large warships did not always take their rifles with them but that the USMC weapons were stored on the ship and could have been marked with the ship's name. Marines were issued these weapons.Attachment 74207Attachment 74208
