guys,
E-mail me with the prices you have been quoted for your extinguishers,including size(usually 2.0,3.5,5.0 kg,the latter being the better/bigger). I'll see what sort of prices I can get.(see www.fmsservices.com.au)
That puppy up there is a 10.0 kg and came fitted with the valve(a bit sturdier than the o-ring on the spindle in the handle). Haven't tried to fit a reg to it as yet.
extinguishers require a pressure test every 6 years.
