The Goldberg Bucker was a kit, 65" wingspan (I think, memory is getting old). A couple of the Import ARF dealers had your Bucker for a while, both in white and yellow and blue. I almost bought one. Just never pulled the trigger.
There are a lot of clones of the Goldberg Chipmonk out there. If your 's is a Goldberg it is an execellent flier also.
