Any of y'all seen this one? I picked up a copy today because it has the best illustrations and explanation of the function of Metcalfe's cartridge block, rifle attachment, etc that I've ever encountered (a guy could go a fair distance towards re-creating one from the illustrations, though without more dimensional detail it wouldn't be correct).
Delving through the book there is some interesting detail on alternative packs that were considered, cartridge belts and boxes, the apparent first official adoption of foot lockers, first issue of meat cans, and the pro- and con- arguments about the adoption of the trowel bayonet.
Kinda neat.
The seller had the next in the series, 1874 Cavalry, but I've never been a horseman so I passed. Lots of books dealing with WWI and later, a few bayonet books, a few knife books. Nothing else I wanted to read badly enough to buy!
The copy I picked up is almost certainly a reprint but not marked as such; the Calvary book was marked as a reprint.
No luck finding books on the .50-70.
