I'm posting this pic in all the toy forums I belong to hoping to solve the mystery. I think the red part is a wing to a Gundam or Macross, so if you need it, it's yours. The 6 black pellet things may go to a Gats Blocker, and the radio backpack is hollow. It may be a Sgt. Rock vs. the Bad Guys accessory? Thanks for looking, and thanks even more for helping.
Isn't the red wing from Voltron? You know the lions...I can't be totally positive cause I'm out to sea but am pretty sure. I cannot help with any others sorry.
Update: The red wing was for the black Voltron lion, and has been claimed. Rumble's right, the gun is for a Bucky O'Hare, whoever that is. Headless blue guy is Luke Duke. The grey thing next to him goes to a fast food Lego guy named Nick or Jens. I have both, if someone wants 'em. Someone thought the radio backpack went to the Corps, but not sure. And the part above the Bucky gun may go to a Gundam guy's head. Thanks for helping! Those pellet things and big black gun are bugging me still. If someone sees a part they need, let me know!
