25. I had Tommy's problem (Eli Whitney had an assembly line of sorts, and made weapons), plus a couple modern military weapons I never heard of. And whoever thinks 'pistols at dawn' signifies flintlocks has a 'rarefied' view of the subject.
I watched an old western with Burl Ives and it had the gentlemen guns for the morning dawn shoot out. Burl shot his own son for cheating and grabbing a six shooter after he missed with the gentlemen single shot.
