Roughly 3 years ago, I bought a rough, primered, fiberglass Fett casting off eBay from a "KBoyette". At the time, the price was right, I knew I could make it nice, and it looked good.
I just took for granted that it was probably a DP Deluxe recast, but as I set about cleaning it up, and started having to really look at the details to repair them right, I started noticing more and more discrepancies-
The DP visor was shortened by roughly a 1/2" on either side; Mine went all the way back.
The DP's had pre-done battle damage- scratches, bumps etc. Mine, while rough, had no real pattern to it's texture, and was more indicative to me of a well used mold that's surface was nearly worn out, rather than deliberate damage.
Also, it was noticeably larger than any of the other Fetts I'd seen.
Finally, around January or February last year, something in me ganged up and said "ASK AROUND about this thing", so I posted a thread on the RPF
called "Sarge's "Mystery Helmet", asking people what they thought it was. After a week or so of debating, someone, who's probably forgotten more about SW armor than I'll ever know, posted that he knew what it was, and that my original was one of 10 bootleg copies that were made by Don Post employees while they had an original film used helmet in their possesion for laser scanning. This was for the development of the DP Deluxe Boba.
I was amazed to hear this, and of course patted myself on the back for having a good eye.- When I bid on the auction, I had no idea what it was, I just remember looking at the pics and thinking "Yeah, I like the proportions on this one- it LOOKS like Boba!"
