Well thats cool! My dad has a bunch of photos of my airplanes from that era in a photo album somewhere. It was all way pre-digital cameras so I dont have any.

I believe the one in the pic was one of the last 2 LA-1s I owned. I had a pair or very lightweight ones. I believe it had a Challenge 3 or 4 stab in it. Always experimenting, I dont think it did anything.
Geoff painted that one, and come to think of it I think he painted all 5 LA-1s I had, but that one and its twin were the nicest looking of all of them. They are the two than ended up in Mexico.
