I did all the work to it. The comb is about 1/2" higher than it would need to be because I threaded the barrel for a suppressor and installed an appropriately high rear sight and front sight ramp.
Believe it or not I've been mulling this over all day at work on account of the ridiculous prices. Saw a 22 Hi Power/.410 takedown combo on a gun sales site for $2500 last night, sheesh. I've always been intrigued by the takedown version of these rifles and kind of wanted one even though it would be a single-shot for a lot of cartridges.
While completely overhauling that old 1899 and learning how it was supposed to work so I could fix some issues it had, I marveled many times at just how some of the machining operations had been done. It must have taken dozens of setups in as many machines just to shape the receiver, and if I recall correctly there was more than one machined surface that totally baffled me as to how it was done. Stuff like 3/4 circular cuts that could only have been done with a single-point tool that worked like a shaper (complete with clapper box) but in a rotary fashion. The bolt locking surface had to be notched with a shaper. NO idea how the arched breech recess was cut but it wasn't from the front or back. No wonder nobody will re-produce the action, it would be damned near impossible to do half of it with a five-axis CNC and a 200-cutter library. The lever alone is a marvel, not just of machining but metallurgy: It's deeply color-case-hardened but is more than a piece of iron, it has a very precise spring temper to it to provide positive lockup and has to have a good bit of strength as it serves as one leg of the triangular breech buttress. Taking an analytical trip deep inside an 1899 is to gain a special respect and appreciation for it's rather eccentric and somewhat disturbed inventor.
