I owned the Nelson prototype rifle the safety is not in the same position. How does it look next to a 1920 safety? The shotgun is not a perfect match.
The rifle long beard king has is interesting as well but I have not seen the safety mounted stictly in the wood like yours.
At first blush your rifle looked like something a talented firm made like G&H and thier competition , I have also owned a rifle in the no letter range that had checkered cheeks and it to looked right to me.
