I was wanting to build Habu as a model for years. I did collect some photos that are on an old hard drive that I misplaced. I mostly got them from searches on the serial number or Tired Iron Racing Team, Earl Ketchen, etc. But I will look for them.
I was wanting to do a model in 1/24 and I was working backwards by purchasing the commercial decal sets that already had the checkerboard details that I could resize. The custom name and graphics would need to be professionally made. I remember that there were a lot of names on the landing gear doors. Also, there were minor changes to Habu over the years. I think that the interior was more like the Cavalier executive Mustangs with red leather or vinyl. Also note the change to a cut down canopy and new snake on the wingtip.
If you ever make the decals available (with permission etc) update and I would buy a set. I don't know who has the rights to "Tired Iron Racing" now.
The plane was destroyed with Ketchen and a passenger. But now I see that the ID/wreckage is in the UK for a rebuild.
