Funny was reading my posts and I wrote WW2! Oops, don't worry I know that this gun was used in the first great war. As for stock markings it reads "930 RS 1916" next to that there is III*.

The Ross and I shoot well together. I've shot as good as 1" 3 shot groups at 75 yards and regularly shoot 2" 6 shot groups, with factory ammo. This gun fits me well and it seems I may be spoiled now. I bought a '43 longbranch today and we'll have to see if it's as good as the old Ross!
