Failed Gun Yoga: The Fagnus Revolver

Produced by Alexandre Fagnus of Liege, this is a military style, six-shot, .450 caliber revolver with a particularly interesting and unusual unloading mechanism. The rear half of the trigger guard is a lever which can be rotated 90 degrees out from the frame, unlocking the barrel and cylinder. The front half of the trigger guard then acts as a second lever to pivot the action open around the rear sight and operate the spring loaded ejector star. The gun dates to roughly the late 1870s or 1880s, and I was not able to find any information on production quantity or even the specific cartridge it is chambered for.
