It seems doubtful that it is a P14. The P14 was a Mauser-inspired redesign of the Enfield, but because of WW1, England never really got it off the ground. Vickers made a few, but most P14s were made here in the States, by either Winchester, Remington or Eddystone. Then when we got into the war, we stopped making the 14 and did a redesign to the P17, using our 30/06 service ammo. Doesn't really seem like BSA would have made any.
Pretty fair article on the P14. http://www.surplusrifle.com/shooting...rn14/index.asp
