We have on the left, upwards: Joslyn (rare), North&Savage, Savage "Number Eight" and Rogers & Spencer.
In the box a Dragoon Colt 3rd model. On right-hand side we see Pettingill, Starr simple action, Allen & Wheelock with cartridge with a funny system of ejection, and Starr double action. All gauges 44.
Below the box there is Savage Navy calibre .36, then two others of which I do not remember any more the name. They were not used all for the army, but they all are of the "military" models.
