I think 'EZF is at Redhill. Certianly was a few years ago.
Treaders: Your mention of the Ulster Sealand reminds me of its register companion G-AKLV, which Ralli Bros used to operate. Most of the standard reference books say this was scrapped at Rochester shortly after being shipped home from Pakistan in October 1957, but it wasn't. I recall its fuselage (at least) arriving by road at Portsmouth Airport one afternoon sometime in 1960/61-ish. It was stood on its gear alongside what was known as the 'Corporation Hangar' for some time, but I don't remember what happened to it, nor why it was there. Nice looking amphib, the Sealand, a close rival to the Mallard in the beauty stakes for me.
