Hi all. I have just bought a 1915 dated SMLE complete with magazine cut off, volley sight (minus peep sight) and a 1915 dated bayonet. The butt disc is stamped 'B.U.G. 1951'. Can anyone tell me what the letters stand for, is it a re-issue disc and where can I get a replacement peep sight without paying over the odds? Thanks for any help.
