Ramp Tramp, Not quite correct there. OK anorak mode on......
The CL-44 was a Bristol Britannia license built by Canadair. They put a 13' plug into the fuselage of the -300 series (which had already been extended by 10'over the 100 series) and replaced the Proteus engines with Tynes.
Only the D4 model had the swing tail.
I think it was Conroy who did the Guppy conversion.
Anyway, they were all lovely aeroplanes. Anorak mode off.
