Looks like a really nice well used 4t tower06! As to the maker - M47C on the butt socket = BSA shirley. I would presume the NZ means it was in service with New Zealandicon at some point.
Good luck on the project - if it was me I'd be leaving the wood etc as it is - an old gun which has seen a lot of service! Isn't there some suggestion that some israeli front pads are a different configuration to the british made ones?
