Excerpted from description:

"Exceptional first year of manufacture Mannlicher-Schönauer mod. 1910 rifle delivered by Österreichischen Waffenfabrik-Gesellschaft Steyr to the Army & Navy Co-operative Society, Ltd.

It's the first export model for the English market... The rifle is built in the so-called "take-down" version or more precisely "detachable stock", an ingenious disassembly system that has the advantage of retaining the original headspace while reducing the length of the assembly to that of the stock. This system was immediately adopted by Westley-Richards in 1912 and then by H&H, which used it continuously from the 1920s to the present day."

Grand Dad's M1910 TD also has the grip cap storage with spare sight bead as well as the 'special folding peep sight', which this one does not. I find the rebated front sights to be rather interesting. They seem to be more prevalent on earlier, British proofed, MS than on others. Mine does not have the rebated sight and may be an 'Army and Navy' as the case is identical to the blocks and hardware.
