I recently shared this with the members of TDH, but wanted to share it here as well.
After 11 years of trying, I was finally able to acquire two pieces for my collection at Comic Con this year; castings from the inside of Boba Fett's vacuum formed gauntlet shells. To the best of my knowledge these are the only castings of Boba Fett's gauntlets with direct lineage to the originals that are in private hands and I am absolutely honored to have them in my collection!
I wrote up an article, talking abut them in depth at TDH. You can read more about the gauntlets here:

Hope you enjoy seeing them!
