Most of mine were Scientific. Hollow log variety.
I did have one of the Goldberg models. It was the Little Toot biplane. Everyone loves a bipe!

Sorry no pictures. I used the aluminum silver mettalic Aerogloss dope to finish it. Boy I do wish I had taken at least one picture.

Pennvalley may still have the kit for sale:

Mine flew well but was no stunter. Large loops and wingovers. I didn't try inverted with that one.

Sure looked great in the air!

P.S. They appear from time to time on $bay. There are two there right now. Both look like new kits.
