I used the Spitfire spinner from the Top Flite Spitfire for the two-blade. I have a more scale like spinner that I run on the three blade that came from Gene Barton (made for the Anderson LA-7). I used a few Anderson parts. I got an Anderson Canopy that is much more scale, and I used an Anderson scoop.
6" wheels might be scale, but you could have some trouble fitting those on. I think I had to go a bit smaller (5.25" I think). If the wheels use Robart tires they will fit 5" - 6" tires.
