Word!
I would surely have a redundant system nearby, and these dives take place in a quarry under pretty controlled conditions with safety divers and photographers. Supposedly the news showed up last year.
Anyway, Lottie your stuff is definately in line with what I am talking about. If anything it is even better because it was something that you know the history of and have ties to. Maybe you can use that as a start to your own collection.
I am acutally looking for an old school mask right now. I figure if I am going to dive the double hose reg, I will have to get the rest of the old vintage gear to go along with it. Old horse collar BC, plastic hard pack, double 45'ish tanks and whatever else I can find. Maybe a Creature from the Black Lagoon to pose with as well.
