I have 4 brand new Nitrous/CO2 Bottles all in red with EU Valve Taps.
All have been tested & stamped and won't need testing again till 2016.
They are 2Kg bottles pretty much the same as US 5lb bottles.
£400 for all 4 including postage.
Could do with them all going together but will split if theres enough interest.
Cheers Rich
