The breach of the Disappearing Gun was working so I borrowed Janes camera and took some video of the guide (and I think Neville Ritchie) operating the breech.
Closing the breech
The development of a successful breech mechanism was the key to development of modern artillery. Armstrong’s original breech-loaders exploded at the Battle of Kagoshima in 1862 (part of my Japanese work) setting back development several decades. I thought showing the breech on a later gun might be of interest.
