You know that means you need to post pictures here? Congratulations!!! I can't believe no ones replied to this yet?

I don't own a lee speed (definately buying the next one that catches my eye though..) but i'll see how i can go.

Books: I haven't heard of any. There was a fellow in 2010 saying he would be publishing one but i don't know what became of that.

Where they were shipped to - that would be a case by case on individual rifles. If yours has a retailers name (Army Navy, Westley Richards, etc) then you can contact them with the serial number and it will cost a little but they can check their records and give you whatever info they have written down - this can include date, who bought it, details on the rifle, and where it went.

Rifles and parts - you just have to keep your eyes open online and at auctions. I guess you can use parts from any old Lee Enfield if need be (for various spares).

Building collections of them: Why not? They look good, they're collectable, market for them, popular. Go for it

Hope this helps,
Cheers,
Ash.

PS: Go through this Lee Speed section of the forum - lots of nice rifles, some good pics of them used on game such as buffalo too!
