I recently acquired a new 1894 Legacy in .45 LC. Fired 3 rounds (the first, and only that night ; somehow, in loading, one cartridge "fell" down beneath the ramp that feeds the round into the breech, wouldn't feed back into the mag tube, and couldn't fit back out by the lever. I had to drive a pin out of the lever to get enough space to get it out. A small shim-type washer fell out and I am unsure which side of the pin it is to go on for reassembly. Is there an exploded drawing of this gun available out there? I'd appreciate any guidance.
