A very well done article, Dan. I've been thinking about reloading some cartridges with new film, and shooting my Instamatic 500. Had an X45 back when I was in the Navy because no one would steal it. It was great until the winding mech broke, then I switched to an X35, and put an adapter on it so I could use electronic flash.
