Mr. Brown:

Thanks for the info which seems to parallel what Wirnsberger penned. Basically the procedure changed and the marks remained the same. The "Crown" over "PT" around 1900 was for semi-smokeless T powder and after 1923 was for a presure of 12k psi at the 1st pressure point with smokeless T powder. Are semi-smokeless T and smokeless T the same and when does the gun in question date? Last the barrel maker had to put his name on the tubes(post 1923??) or the proofhouse would stamp them as foreign tubes as ARME ETRANGERE.

Kind Regards,

Raimey
