BahamaLure: You could probably glean the disassembly procedure from numerous threads but I would suggest you invest in at least one book- "For Collectors Only, BritishEnfield Rifles
, Volume 1, 3rd ed., revised, SMLE (No.1) Rifles MkI and MkIII" by Charles R. Stratton, North cape Publications. Great little inexpensive book available all the time on e-bay. There's a picture of a 2A or 2A1 on the cover. If you get bit by the bug and acquire more of these rifles it will come in handy.
