Yep this is from the butt stock, took some time but now I remember the front one had the thread part removed and it was silver soldered to semi circular piece of metal and sweated to the barrel. This is why i'm trying to find an original front one to get the pair to refit.

Rory thanks for the help mate on pictures
CTW thanks for that I do feel its period correct and used by savage but we don't get a lot of bits and pieces down here to check it against
