If Gerry Briley is correct then for reasons of posterity, someone from Gerry Andersons production company or someone like Carlton Video (who own most of the distribution rights to Andersons works in the UK) should get out to Saudi Arabia and locate these missing episodes. failing that, if Gerry Riley can locate those betamax tapes then he could approach Anderson or Carlton and offer to sell them. It'd be a shame to miss this opportunity to preserve these episodes ( i for one have never seen this show as it was made years before i was born) and i'm sure someone will make Mr Riley a handsome offer for those tapes. If anyone knows how to contact Gerry Anderson maybe they can make him aware of this?
