If you are thinking of shooting it, yourself, it would pay to have it head spaced. Most gunsmiths should have go/no-go gauges in .303. I don't know if the Enfield bolts are serial numbered to the receiver but that's a good place to start. Look under the barrel for any import marks - they would be the faint or tiny electro-dots and should say who imported it ("CAC", Navy Arms, etc) If there are none it will be worth more to a collector.
