If you have a GLASTAR you should be a PFA member - if you are you will find all the info you need in PF. If you weren't a member when you bought your GLASTAR and you are now, search the PFA website for the details you want.
Failing that and as a last resort, phone PFA HQ at Shoreham and speak to Ken as he did all the background work regarding European entry permissions.
