Here I am back again, after all the help you guys gave on the Predator cannon and backpack to ask about something else.
I recently obtained castings from original Boba Fett gauntlet shells, the only set currently known to exist in private hands. We posted up an article about them on TDH. You can read it here if you are a Boba Fett fan.

In looking at the right gauntlet in particular, it feels like the entire top of the gauntlet is just a vacuum formed copy of a model part... possibly the frame or hull of a tank or vehicle. I don't know, but I feel like with a bit of effort and your help, we can probably identify this piece, or pieces. Please take a look and give me your thoughts!
