At this point the question is really are you having buyer's remorse? If you're happy with the price that's all that matters, if you're buying as an investment you probably won't make much if any on it. Prices have been going up on these rifles for year and will eventually top out if they haven't already. If you're happy with the rifle and not upset about the price then you did fine. Regarding the non matching numbers, I wouldn't buy an SKS without matching numbers, in fact about the only rifles I would consider without matching numbers would be a Mauser 98, Garand, M1 Carbine, something along those lines. Mosin or an SKS with non matching numbers and I'd pass but that just the way I am.
