Thanks mate, I thought it was the Boeing at first sight, but dismissed it 'coz the missing centre fin until all other manufacturers had been exhausted, only then did I look at the 314 again and found their experiments with different tail configurations!
Unfortunately it'll have to be an Open House as I have to go out for a couple of hours now! LM, Reg go for it!
Edit:
Do you actually have a Sunday off today?
I thought I did mate until five minutes ago!!
