1949 remington model seventeen typewriter with a brass u.s.navy identification # plaque on the side

i have a 1949 typewriter that was attached to a desk with a hideaway compartment for it. the desk has a handle in front where a drawer would normally be. you pull on it and up pops the typewriter.  the desk is made out of mohogany i think and is in good condition. the typewriter itself is a remington seventeen it is a little dusty but in good working condition. on the right side a small brass plaque has been attached that says u.s.navy 100 above the numbers 000954.
