I am one of the organisers of a number of V Force reunions. Our most recent reunion last year was well attended by ex Valiant guys, and I am sure the same will be true of next year's event. If you want to visit our website
V-Force Reunion you would be welcome to leave a message on the guestbook asking for any ex 543 Valiant people to contact you. Cant guarantee results, but it would be worth a try.
