I'm a "lurker" here, currently not building anything, too many 1:1 scale projects, but thot I'd chime in on this one...
Woolfster, do you still want scans of the instructions for this kit? I have a complete one (unbuilt) that a friend who owned a hobby shop got for me, and I will get them scanned tomorrow (Tuesday), along with the little booklet that tells about how it works and all. This kit is extremely cool, and goes well with my (also unbuilt) auto chassis. Sorry I didn't see your request earlier, but I was working on a Visible V8 Chevy, among others (those 1:1 scale things I mentioned earlier) If interested, let me know and I'll forward.
Best regards,
Tom
