LowNSlow,
OK, agree that only the D4 had the swing tail & confirm that
Conroy did the Guppy conversion. (Only 2 & one was written off
many years ago leaving only what was originally N447T)
There has been long discussions regarding the 'licence built
Britannia'. Although based on the Brit design, it bore only a passing resemblance & parts were not interchangable.
Never did get to the bottom of that one. Anybody else clarify the
situation??
