1892 Trials barrel diagrams.

I was cleaning up the hard drive on an old laptop. I don't remember where I found and captured these 1892 illustrated Plates.
They are probably from the appendix of 'The Chief of Ordnance Annual Report', for 1892 or 1893.
(I don't recall why plate #3 is missing).
The two .30 caliber "Springfield" barrel diagrams likely show Trapdoor test barrels.
(I threw in a couple of 'bonus' photos related to Gen. Mordecai, who signed the plates and was very influential in tooling up for the Krag at SA).
