Freakin cool! Thanks for posting the link. I already knew about some of these but wow! Never knew there were so many!
Agreed, Truly mind-blowing stuff, I knew about air rifles that dated back to the late 1500s, but never imagined they would attempt to incorporate the technology into military artillery, and actually use it.
