Well Thank you! As I said quick bunch.

Yeah I get the pump, he just wants the motor the three stage is cute! I don't know about the fire extinguishers, those are pretty dangerous from what I hear - filled with carbon tetrachloride, talk about a cool way to die! Have about 40 of those - how would you ship them? If one broke in the mail.... bad news.

LOL – leave me out of the average! I have been wondering how to determine what is inside the bottles – I was under the impression the carbon tet ones were marked.

Not to get O/T or boast, I have 18 years in the fire service. It is amazing to see how fire fighting equipment, methods, and technology has changed in a relatively short period of time. Yes, carbon tetrachloride extinguishers are dangerous, as are any old, loaded, soda/acid extinguishers. They (soda/acid) were riveted seam and made from copper. I collect, when I find and can get, antique fire equipment. I have a carbon tetrachloride extinguisher. I have a few old (empty) soda/acid ones. One still has all of it's internal components, acid bottle, cage and lead stopper. Many old soda/acid extingiushers get new life as table lamps. The glass bulb fire extinguisher looks like one that a frined of mine has. It was in his grandmother's house. It has a spring loaded hammer held back by a fusible link that strikes the lower part of the bulb when the link melts. They were commonly placed high enough above stoves that heat from cooking would not affect them, but fire would. The glass bulb could also be taken from the holder and thrown against the ceiling or wall above of the fire. Sort of like a water baloon.

ER, thanks for some interesting info. Re the carbon-tet extinguishers, are they so dangerous? I know many an old grey funnel or merch seaman who used to use a bit of CT to spot clean their dress uniform

Not being a safety expert or chemist, the carbon tetrachloride extinguishers are PROBABLY more of a danger if used on fire or leaking than just sitting there.

Sort of like old munitions, until it/they are handled or messed with, it PROBABLY won't do anything.

The carbon tetrachloride that was used in fire extinguishers was no different than that which was used in the dry cleaning industry, probably why they used it to spot clean their uniforms, until it's health hazards became known.

The glass ball may or may not contain carbon tetrachloride, but I wouldn't want to find out!

The link in Kenb's second post tells a bit of about why using a carbon tetrachloride fire extinguisher, exposes the user to hazards.
