Which '03 am I looking for? (Navy use)

[pmclaine]

The rifle looks as if it has the reverse safety found on some National Match rifles. Also it looks as if the bolt is polished.

Educate me regarding the reverse safety please.
The bolt does look polished and may have been but it is a WL3 not NS. There is no serial marking of the bolt and the barrel lacks a star gauge. The stock is marked with an S in the cutout but it lacks a serial number and drawing numbers. The barrel and reciever may have been an original set (8-31 SA Barrel) but the balance is mixmaster - a rather well cared for mix master that I am happy to have come into.
