Hello Roger and Tony,
Attached is another shot, (poor), of A8-363 at ATU.
There is a yellow fuselage band as Roger says there should be, although not in the position he suggested. Seems to be in 'stock standard' position to me.
The 'thing' behind the tailwheel is not apparent in this shot. Maybe that and the 'bump' forward of the tailwheel are something behind the aircraft in Tony's photo. Or were they mods for a particular trial? On the original you can just make out the cover fitted on the port side of the tailwheel to prevent fouling the cable.
Tony, I have other photos of TT Beaus that may help with your model. Let me know if I can be of use.
And if you get a good copy or scan of that photo, I also would appreciate a copy.
