Indeed, the Bristol Britannia is my absolute fave turbo-prop as well. As it happens, I have a few really nice Corgi 1:144 ones, and the 'white tail' BOAC Britannia 100 series is one of them. I seem to remember mentioning this before and you posted a photo of the two (100 & 300 series) you have/had. Of my BOAC ones, I only have the 'white tail' still. What a cracker!
I find the 1:200 renditions tempting
, as the engines are a better interpretation, but I find all the makers missed terribly on the main u/c, which is quite unique. Pity. Then, many of these makers are also adding fuselage hatches, etc., where there never was any. (Odd?
Anyhow, at least I have the Corgi ones, and my 'library' of Bristol Britannia reference books -- including one published in 1958 expressly for Transport Canada to be distributed to Canadian airports on behalf of Canadian Pacific when they introduced their Britannia 300's. THAT was a super-rare scoop!
I hope you can find a replacement for yours.
