Got a free gift of about 15 fire extinguishers, only problem I can see with them is that their out of date. I'm going to keep a couple handy, but does anyone know of any use for the other ones? Little compressor tanks? If I had cut the top a bit longer of the one in the pic it woulda made a compressor air filter. There are little pressure gauges without much scale,
valves on them. Anyone want any bits for the postage price?
