We have a winner! Congratulations to Lauren who guessed (http://tombanwell.blogspot.com/2009/02/rayguns-raughnold-model-81.html):
Hey Tom, here's my guess:Particle Accelerator- air nozzel
Pulse Detineator- body of a lamp
Leather Grip/Handle- sink faucet
Exahst Port- trophy base and a chess piece/rook
The object that no one had guessed was the trophy part. My clue "The one found object that no one has yet identified will be recognized by winners." referred to winners of competitions would recognize a trophy part.
Thank you to all who entered. It's been fun for me, and I hope for you. Congratulations to Lauren for the correct guess!
Above are the found objects in context. Faucet, trophy part, rook, lamp part, and air nozzle.
