"Thanks in advance"...(TIA) For any kind of link to the patents.
I've seen 1700's air powered repeaters, and they had all the problems one would expect, pre-Viton. But an electrically ignited shotgun? WooHoo!
Piezo would be erratic, and batteries had a very short life, and low voltage outputs, in big cases.
I just gotta see how this was done!
Here is a link for numerous 1890's electric gun patents and pictures.......all can be enlarged for viewing....as I just did. On this link there are also some later modern electric gun patents and pictures.
If the link here does not pull up, key google for "electric gun patents 1890's" and it will take you to the link below.
