Hmmm, as my RFD is adding my kit (and spare barrel) to his US order, the kit will "officially" be coming from him .... With that in mind, I think it will need to be proofed as it will go through his books??

I seem to recall you saying Peter, that the original kits were proofed out of the rifle, some sort of jig I would guess??

Or is it two Germans, one holding the liner and bolt group together on a bench and the other with a proof round and toffee hammer!
