Hi Gents. Everyone who finds something different wants to believe its experimental. This gent has not been exposed to many Long Branch Mk I rifles. The safety, the bolt, the butt plate (brass of all things) are wrong. The bedding I'll bet is ridiculous if I heard him correctly. You want the barrel to sit firmly in the bottom front of the fore where the wood is proud. Not spring loaded up - that is SMLE bedding. So the rifle has been worked on my guess by an English smith. There were no experimental LB rifles until production expectations were being met then some things were tried out on a limited basis but only a short fore sniper made it out in the field. Did I see a BNP on the left side of the body? What no LB view marks on the wood? This gent is hoping he has a treasure but in fact its a lemon. The 1941 LB rifles were made to the Trials No. 4 Pattern but with no cut off. Thats the fact Jack. John
