I found this at a garage sale. I think it must have been some kind of home made kit. There is a picture of one of these in Sven Kirstens book "Tiki Modern", on page 225. The caption in the book mentions "hobby projects", which makes me suspect it is home-made, but as it is the same as this one, there must have been some kind of kit or set of plans. Leave a comment if you have any additional information.
