Dear Rick Morris, yes, I have seen a complete set of these "fire bombs" as you have described. I was in an "antique" store in Cloudcroft, New Mexico and saw a set of six, clear, glass globes, ensconced in a thick wire frame, looking much like a 'six-pack'. They were made of thin glass, and there use was what had been described to you by your local expert. They were baseball sized, too, and filled with a colorless liquid (what I could see at the time). These "fire bombs" were represented to me as coming from the late 1800's. Please, understand that I am NOT an expert in this, but simply saw an example. My suggestion would be to ask around at local antique shops for some one who collects antique fire extinguishers. Yes, these collectors are out there. But my best guess would be oil lamp chimney glass, too. Good luck. Joanne Reiter.
