Win a Raygun: More Clues

There have been some good guesses, but no one has nailed all five found objects yet. Today I will post three clues, which should make it considerably easier. My first contest was won almost immediately, so I wanted this one to be a little more difficult.

First Clue

When I first announced the raygun contest (refer to it for more photos), I wrote "In the model 81 there are five objects that I can identify." As many of you have noticed, there are actually six found objects, but one of them I cannot identify, so it is not included as something to name. It is the silver colored power generator shown above. It has been guessed as a part of a flashlight, a television knob, a dial from a stove, etc. Please ignore it in your guesses. It is a collar of some sort as it had a large bolt sticking out of it, but exactly what it is I do not know.

So the parts you are guessing are the particle accelerator, pulse delineator, grip, and two pieces making up the exhaust port.

Second Clue

None of the objects is made of wood.

Third Clue

Many of the objects have been guessed correctly, but there is one item that no one has guessed. Think of something other than any of the previous guesses. Good luck!
