UFO Mystery Ship

I found this one night while digging thru an old box.  I'm guessing I built it 25-30 years ago!  As far as I can tell, it's complete.  The hangar bay doors still have their hinges, and the shuttle is still there!  The glue has discolored the plastic, but it was never painted. This kit is currently available for trade.
