IIRC, this is an older gentleman who posts over on YORF.
If you can find his post he has his email listed for direct contact.
After collecting for over 50 years he is in a place he feels it is wise to liquidate his collection.
Wow!
I guess the one I still have in the bag should be worth a lot when I put it on the market LOL!
Centuri's SST Shutle was & is one of my very favorite Shuttle designs. My original was unfortunately distroyed by vandals back in the mid 1970's. I Replaced it with one of my collector kits in 2007 to complete my Shuttle fleet. It like the 1st model is an outstanding flyer and the little shuttle glider circles the mothership fairly closely on the way down.
