Hi joe, Im on a get rid of blue faces mission tonight, normally its stamped on the bottle, ie. 13kg etc etc. sounds like yours is a bit smaller? have a look!

Hi Joe, ok, is the bottle blue or red?
calor gas (blue) come at 4.5kg/7kg/15kg (butane)
(red) come at3.9kg/6kg/13kg. (propane)
if your bottle fits into a recess outside the van,then I guess it will be a 4.5 kg ( about 12in high).
Hope this helps
Nick.
