All Nitro Proof stamps have a "P" after the N so it would be crown over NP. The crown doesnt quite look right, with your permission I'll e mail the pic to Bill Harriman at Shooting times and see what he says. Got me started now, I dont normally bother but as neither mark is shown in Skennerton or the Collector grade stuff I am caught!
The crossed flags are inspectors marks, military proof is different to civilian marks. They are inspectors crossed flags with a P below or an N for british Naval. The only use of crowns is either a civilian proof act stamp or a Govt contract factory stamp and they would be on the wrist/butt socket. P on its own can mean replacement barrel or paralell bore?
The crown does look like theBSA Shirley crown on repairs or conversions but it would then have BR underneath.
As stated above if an N on its own it would be Naval but that doesnt explain the scrubbing around the solitary N. I suspect its a Nitro proof from that year 48? and its a poor crown stamp. I'll e mail them off!
