I remember reading in an old RCJI review on the "Rookie" that the coca cola bottles in the states are slightly different. UK bottles are found to be taller and thinner. This will save multiple journeys to the shops trying to source one, hopefully the offer to send one over might be possible. It is worth while have good contacts on both side of the pond since many Jets items can sent over each way as "gifts" with no or little tax! This has been my experience from contacts in the US and Canada. If you really get stuck I'll ask my son to post one from Toronto. Even our VAT man will be stuck making a charge on a empty bottle of air.
