I found tons of reference photos and decided to start with these. Note that the drawing has 7 of the electrode do-hickies while the images of the replica has 6. I decided to go with the 7 in the drawing because they look cool and more is more gooder! Here are some AO renders. I must have done 5 different versions of the bottle connector before settling on this version. I was just experimenting with stuff and changed up the front part of the thing that looks like a tuning fork is stuck into. It's quite different then the references. I might keep it or I might remodel it. I really like the kind of mechanical / organic form of the barrel section. One of the reason I wanted to model this gun is to see how I would handle modeling that section. It was an interesting challenge.
