I go by the reciever which has an Enfield Serial and 59 date. some other parts are D59 marked. All My brit wood is BSA B1960. The wood I got before I got the rifle as I was expecting a BSA, but even happier when I got an Enfield one (Cheers Anglo !)
I had mine with suit at the range yesterday, all on a target on my own. After a few cracks with some Federal I was totally surrounded by club members wanting to have a look / go. I managed to get a video of a group I shot which I will have on my YT channel soon.
My FAO is happy with this rifle, I am happy, so no issues here.
