Why not? You guys have been working hard on all the obscure stuff.
Not that this isn't obscure, in it's way.

The usual questions: Who used it, what is the whole item (not just the closeup portion), etc.
It's on the net, in several places, too - not a complete cypher.
Update: Okay, John S, the gun dealer who *sold* me the rifle, gets it correct.
Rifle, Short, Magazine, Lee-Enfield, No 1 Mk V. An experimental rifle that led to the No. 4 Mk1 of WWII fame.
Fuller view of the receiver here.

This is the rifle that usually holds the rifle-mounted barbed wire cutter. Which it *never* did in service I might add - I just have more stuff to stick on my No. 1's than I have rifles...
Jim B's crack about Australia is actually on the mark - many of these rifles *did* find their way to Australia - this one did. It sits in a No 1 Mk III stock (incorrect for the rifle, technically - the Mk V had an extra reinforcing band and one-piece upper handguard) marked to the New South Wales police.
