You should try contacting the Brothers of the Third Wheel. Maybe put an add in their newsletter. I'm sure one of them knows where that trike is.The AEE Covair Trike sold a few years back and ended up supposedly in LA and was to be restored. I could never make contact with the new owner at that time. I would like to find it and the owner and see how the restoration is coming along , if at all.
I figure if it's in LA someone must know where it is. I'd love to put info about it on my AEE web site and blog.
