i am going to AJ2013 (23 australian jamboree in maryborough) and i need to raise funds to pay for entry. i have been looking through the cupboard trying to find things to sell. i remebered this which i bought for $15 at a garage sale a few years ago. if anyone could help with identification of this and how much money i could sell it for that would be awesome. it says that it is quell fire fighting equipment, automatic, and made in 1957. it is a copper tank with copper rivets, a brass screw lid and rubber hose with brass fittings. my estimate on the capacity would be about 9 liters/2.5 gallons/20 pints. i think that you are meant to hold it upside down and the weight of the water pushes it out the nozzle. i dont know if that is right because it doesnt come out very fast.
