I hope someone here knows a little bit about these guns. A friend of mine has a pretty beat up old british .303 rifle that he wants to get rid of. I'd like to fix it up a bit and wat a cheap rifle, but I want to give him a fair price for it. I told him I'd look up what they were going for, but unfortunately I am having a hard time. As seems to be the case with me, it's never simple. I have figured out that it's an enfield no.4 just from the way it looks, and it's got the ranged flip-up sight which seems to imply that it's an mk2. The problem is the markings on it. The only markings I can find are up on the barrel at the front it says: 303BUK CAI STALB VT Which as I understand is just import markings saying century arms international, st. albans vermont. Near the front sight it says S76, which I haven't been able to find information on except that it seems like that is just a front sight marking. The only serial number type number I can find is on the metal part of the receiver where the back part of the stock connects to the front part, right behind the trigger. On here it has a SIX digit number 370XXX in large digits. I haven't been able to find ANY mention of a six digit serial number (with no letters in it). I do recall seeing a tiny stamped "B" on some part of the receiver, but it was very worn out, and very small, and all alone. Does anyone have any idea where this gun came from? Or at least how much it might be worth? Prices on these things are all over the place.
