I lucked on a LSA.Co martini enfield a few years ago. Pleasure to shoot, the sights however leave a little to be desired. Check the bores because alot of them are sewer pipes. That joe salter example looks a bit different than mine, as its missing all the markings. Mine had the original manufactures date 1886 with the big VR crown, then its conversion date 1899 on the other side, and its British nitro proof marks and the regiment marks. All those stamps were fairly deep, so I dont see them all washing out, especially the BNP stamps at the front of the receiver.
Has a little engraved shield in the heel of the stock, makes me think it was maybe a club rifle at some point? No ramrod groove in the stock to speak of or provision for handguards.
