I'm with Tamara, get the the No.1 first ( and get the No.4 later). The No.4 is a later model (1939??) that has better sights and makes a better shooter. The No. 1 Mk 3 is more "historical" since it served in both world wars plus countless other conflicts. However, the No. 1 is not a "bad" shooter. I read, on one of the boards, that there was a speed/ accuracy contest in 1914, before the war started, in England. The drill was to hit a 12" black circle on a white paper at 300 yards as many times as possible in one minute, prone, starting with a loaded rifle. Sergent Instructor ( someone whose name escapes me ) won with 38 hits in one minute. This is 38 aimed shots with 3 (2 clip ) reloadings in one minute with a bolt rifle. The rifle was a No. 1 Mk 3 Short Magazine Lee Enfield.
