Pathfinder,
There is just something special about those Enfield No 1 Mk IIIs. I have been shooting WWI and WWII era rifles the past few years and learning their history. That SMLE of yours is probably my favorite. For some reason, while they have better sights, the No 4s don't feel as good. They don't look as cool either. That bolt throw is pretty sweet, too.
You are fortunate yours shoots well. Many had very loose barrel tolerances. Imagine a .311 bullet in a .318" barrel. Hopeless.
On reflection, I think part of what I like about those No I Mk IIIs are the memories of the photos from Afghanistan early on in their war with the Soviets. The pathans walking around the mountains in sandals, homespun garments, turbans, and carrying SMLEs and curved knives. Fighting for their homeland against the invader.
