if I were granted too meet anyone from the past, it'd be John Moses Browning, I would not ask him any dumb questions, would just be happy to watch him work, or listen to him speak/teach.
I build a lot of things with my hands and as I look at this action I think what an accomplishment! it truly is an amazing design that the man created.
BTW, I'd ask all kinds of dumb questions! JMB would probably tell me to STFU!
I'd be content in being that fly on the wall ; ]
