I recently bought a Pattern 14 DEWAT, same motivation as you. Had a hole drilled through barrel next to receiver, with a pin driven in and welded. A few taps with a hammer/punch got the pin out, inspection showed the rest of the rifle to be in good or better condition. Had to go through an FFL dealer when I got it, I think federal law says that you have to do paperwork to transfer a weapon IF IT CAN BE RESTORED TO SHOOTING CONDITION, but just what their definition of this is, I don't know. Most people will go the paperwork route, just to make sure.
FWIW, P14 Enfields are one of the last great buys on the surplus market. Scarce but almost no demand, so prices still low. I got mine for $175, have seen several others go for similar amount. Just bought a second one, already has the ears ground off, and has a sporter stock, also $175. Might consider selling the first one. What state are you in?
