Hi Jim!
A TOUGH question!
Not mentioned so far in no particular order:
Southwick 56" Skylark, T-Bird II (bubble canopy version, Mr. Palmer did win Open but not the Walker Trophy), Caprice
I am guessing you are asking about *Classic* planes, right?
If not, Bob's Saturn, Billy's Juno, Junar, Geo XL, Geo Bolts (P-47s)...................
