That photo above pointed out by S pack shows a particularly rough bit of work.
Anyway, to my knowledge the production A9X shell recieved a "Patch" whilst removed off the production line before being slipped back in as batches. The factory race shells were also pulled to oneside, some slipped back in for trim etc. Others just painted white and put aside as spare shells for Allan Grice (LOL).
And importantly a patch was available to teams to bring their existing L34 race cars up to A9X specification. It was the teams that installed them and I would imagine little care would have been given as they just needed to be functional. But were all the "patches" use in race cars?
Anyway I wonder why it is mascarading as a budgie...................something needing to be hidden in plain view as suggested by yel327?
There certainly is an interesting history to this car.
