<font color='#0000FF'>Thanks Bob,
The travel agents are checking with the airlines to see what the requirements are, I am hoping it will just be that it must be empty with the valve left open, just a case of waiting to see what they say.
Obviously with current events they will have to be 100% sure that it is not a bomb, someone mentioned that the pillar valve may have to be removed to allow them to inspect it.
If I can travel with it then it is a bit pointless if I cant get it filled because they dont recognise the test marks, but hopefully with a bit of talk I should be able to convince them that the UK test is as good as thiers if not better.
In that order.
