Dive Bottle Test - Short & Curly's?

[angrybear]

What is the point? that would mean that nobody would test and pass them as fit for use, keep them as 2 x 6 litre bottles, there are ways to join them via tubing on the valves, which is how divers do it I think, but not permanently "Siamesed"

Surely, that couldn't be taken as anything other than the overt sarcasm is so obviously was
