I was going to say the same thing Matt! It looks just like a modified, monoplane version of a Walrus - and probably was!
Vic, I'm not sure, but I think there is a complete Swift in a museum, possibly the record breaker. It's either at Cosford, or maybe even Sunderland. There's also the Swift cockpit simulator, in the small museum at Tatten Hall, next to Coningsby.
