Thanks guys, I am scribing a letter at the moment, introducing myself as part of the Yorkshire Divers group (afterall the Oonas UK rep even came alng to see Mark on the first night).

I am not going to ask for anything specific, just lay it all out and see what the response is.

dcrapmt- I'm a lapsed chemist myself, unfortunately haven't been in a lab in years. but if anyone can suggest a fine white hygroscopic powder that could come to be in a cylinder then please let me know, samples available on request.

Cheers

Conor
