That's one of the shames when a Ross' stock has been sanded down. The Ross is one of the few rifles that can sometimes be associated with a particular unit during a specific period of time. It is not unusual for sported Rosses to have had their front sights remounted with the new muzzle being lathe turned to accept the sight base. A factory style job. The long 30 1/2" barrel usually stands out.
The only "spare" stocks that occasionally turn up are ones salvaged from the Indian DP rifles that had pins welded through their barrels - like their DP P-14s. Unfortunately, they notched the forends when they installed and welded in the pins. Given an armourer's style patch, the stocks are usable, but their origin is pretty obvious. I have found only one intact replacement stock in 5 years; it cost more than the sported rifle that I restored.
