I say old chap, rather a good show there, don't you know!
Nice find on the squadrons and the build guides old bean, and I see you opened, or re-found the pics I got for you.
If it's not too late, I think I might have a control yoke you can modify to fit onto the control column, as the B(I)8 didn't have the 'fighter' type grip. Don't know why Airfix didn't include a yoke - maybe the (Chinese?) tool-makers worked off some photos for a different Mark, or it was missing the yoke.
Let me know if you want the part , there's a good chap.
