Steve, I fully agree with you: your model issued in 1953 definitively deserves to join the group. And the Mark 11 is also one of my favourite vintage models produced by JLC.
The reason why I have hesitated to include mine is that it is a RAF version issued in 1948. So I have decided to reserve it for another tour: "back to the 30s and the 40s!"
I also would like to use the opportunity of this message to express my admiration of your work. One of your macros is used as the wallpaper of my computer for many years now. And even if it was long time ago, I still remember precisely the moment when I discovered your Launchpad. I spent hours that day watching your photos.
