Okay, I need some help on this one.

Back in 2004 or so, Gentle Giant announced a series called the "Armory Vault". The concept was to do a line of 1/6th scale, highly detailed, helmets. They had a mock-up poster of:

Darth Vader
Boba Fett
Skiff Guard
Scout Trooper
Luke X-Wing Helmet
Snowtrooper
AT-AT Commander
Death Star Gunner
Clone Trooper
Boushh
Death Star Trooper
Jango Fett
AT-AT Trooper
Wedge X-Wing Helmet
Royal Guard
TIE Pilot

Then, NOTHING.

Gentle Giant did make "Scaled Replicas" of a few helmets. These appear to be .45 scale. I have seen images of:

Boba Fett
Jango Fett
Darth Vader (Chrome)

The image I found on another site showed the COA for the Jango Fett helmet as XXXX of 1,000, but that was not filled out and could have been a mock-up.

A local comic shop has a Boba Fett helmet and Luke X-Wing.

I have searched ebay, amazon, GG.com, and a ton of other places (adverts for SSG like Brians, EE, BBTS, AFX, etc) with little to no luck on the line. So my questions are...

Which helmets did Gentle Giant make?
What was the edition size?
When were they released?
What was the MSRP?
Were there exclusives (there always are with GG)?

HELP!

BTW, I am heading over to pick up the Boba Fett today, I REALLY want the Luke X-Wing, but they posted it as "no box" so I haven't made up my mind yet. :-p
