Help me identify these parts

[puckydog]

Hello, Can someone here help me identify the three detail greeblies on the lower section of this helmet's faceplate. These silver cast parts I believe must be stock model parts. Can someone identify them for me and tell me what models they come from? Thanks, Jeff

The one on the right looks like part of Darth Vader's TIE Fighter.
Don't know what the original downer was though.

What helmet is that? Looks a lot like Last Starfighter.

The left looks somewhat like the old icecube tray metal that was used on the original trek phasers.

Yes, the helmet is one I used to own from Last Starfighter. I regret selling it years ago as I now own the costume it belongs to.
