Photo #1 is showing the rear of the cylinder with the end of the teat-fire cartridge protruding through the small hole. The hammer strikes the "teat" to fire the bullet (similar to the way a rim-fire cartridge is fired).
Photo #2 shows the cartridge seated into the front of the recessed cylinder.
Photo #3 shows the loaded cartridge with the barrel back on and the "hook extractor" in the closed position not allowing the cartridge to be forced out. The frame of the barrel keeps the other cartridges in the loaded cylinders from moving forward.
Photo #4 shows the "hook extractor" pushing out the spent cartridge.
In 1869-70, Colt purchased the Moore's/National Arms Co.
Thanks for looking,
