What you have is the best value in rifles I have ever found. I was In a sporting goods store in Charlotte NC. about 10 years ago and saw this immaculate .270, magnaported 22 line per inch checkering, deep blueing and lightly figured walnut stock. I brought it to the counter and asked what's wrong with it, it appeared to function flawlessly. They said it went out a couple of times and came back saying they couldn't get the bolt out to clean it. Seeing it was made by Birmingham Small Arms, same as an Enfield I pulled the trigger and pushed up and it slid right out. I flopped down my 250.00 had a hell of a time finding scope mounts, as you know it has an odd ball size weaver type mount with a 1/4" hole in the top of the receiver and finaly found a mount that fit the dove tail but under recoil the scope would slide forward. I drilled a 1/4" hole in the rear base and lock-tited it in place and problem solved. BSA also had a division that made motorcycles, but the 3 stacked guns is Birmingham Small Arms, a very old Brittish gun maker who also made the Martini-Henry.
I bought a pile of once fired Winchester cases and was shocked by the accuracy of my 250.00 rifle, sub moa with most brands when I did my part and then along came the Barnes X bullet. 60gr H4831sc and a 130 brass x bullet and was averaging sub 1/2 MOA and on a windless day can ring the 12" 1000 gong. I probably have 30 rifles several cost 5 times what the BSA cost: Note it did not shoot very well until I free floated the barrel. What shocks me is the low blue book on the rifle, last I checked it was 450.00 for like new. I wouldn't sell it for 2500.00, a 7lb rifle that shoots sub 1/2 MOA, quite often one ragged hole. If you see one buy it, I have three now, each one bought cheap, glass bed it or if you a bit more experienced in lay it with aluminium. They are all shooters and can't for the life of me figure out why they are so cheap, sure they don't have mauser controlled feed and only two locking lugs, but they make them in .458 Win Mag with two lugs. I don't know what you paid but it was a steal.
