Does anybody have, or have access to, a knackered Crewsaver buoyancy bag? Its the sort of thing that's always lying around in a saiing club - right up to the point where you want to lay hands on one...

Its not the actual bag I need, by the way - just the screw cap.

I have a screw cap if you need it. 

 Yes please! I'm in Brighton (Shoreham SC).  If you let me know how much (inc postage) and how to pay you I'll send you my address.

Derik,
Please email me your address and I will post as soon as I can.
