I agree that "no bullet" notes a choke bored tube for a projectile that can be choked. It began as "NEM GOLYONAK"("not for ball") and I guess in 1966(from data string of 60170/66) was "no bullet". I'm curious if the "rain-drop shaped marking" is similar to a set of horns with a "I" in the center, which was the voluntary provisional proof in the white. Does it have a St. Stephen's Crest over B.P. all over FN(fust nelkuli=smokeless)- final smokeless proof used until the 1950s & 1960s or a wreath minus the center top portion with a star? There's a final proof mark there somewhere. Do the tubes weigh 1.495 kg(3.3 lbs)? Could you post a pic or email one?
Also for those who haven't purchased the text by the British Proof Authorities, Red 5th Edition I think, Google has scanned it and it can be found at:
