Interesting points. I have such a large reserve supply of aluminum and vintage mylar extra crispy material that I have had the opportunity to mangle them both to see if I can replicate those looks. I'll pull them from ye archive and post them soon. You can judge the results.
Have you handled Greg's Hero? How about the other "West Coast Collector" whose name we dare not utter. I have not. My buddy Ron Shanko did and has. (Ron and Steve made the legendary Shanko & Wright aka, the "S&W" Midgrades and Hero's). I asked Ron for a favor to look again at the real crispy during the next few months. He's gonna see if he can help.
This all transpired because Bill, from Kentucky, passed away in very recent times. Bill had a die-set for a pretty good extra crispy. I pulled my John Long foil from my archives, Bills extra crispy, along with my Roddenberry Pewter Crispy, and all the other samples I've collected. I live in Florida, I flew out to Seattle twice to compare my archive samples with Paul Allen's (aka Steve Allen LOL) MoPOP/EMP midgrade crispy (sadly locked in a glass case where I could not get at it).
I have vintage mylar samples and John Longs stamped aluminum foil sample (John insists his is accurate and he based it on his personal inspection of a screen used prop) that I think are most close to what I inspected personally at MoPOP. The J. Long archive sample is blindingly bright and dates about 2006 +/-, the possible mylar/plastic date is not known but has that nice musty smell and must have been in a basement or garage for some time.
I needed a reliable supply of extra crispy material. So what to do?? I had posted that I had a "aquired" a supply of extra crispys available measuring an exact and symmetric die-cut dimension of .97" x 1.30". Where did I get so many? The photo is below....I had a die-set made...read on...
All truth now be told, I paid an tool engraver to make a set of dies, not once, but twice. The first set did not pass muster with me and I had it shipped to me where I took a sledge hammer to it (a little frustrated with what die-sets cost and, I did not want it out of my custodial care). I have a lot of extra crispy stock-on-hand and an unlimited supply in the sense the new dies are carbide and really don't wear at all when die cutting such a thin and soft material.
I sent Ron shako a "gimme feedback ziplock" of these new extra crispys and he felt I "hit it out of the park". I have always liked Ron because he tells it the way he sees it from first-hand experience and, not what he thinks one wants to hear. A few RPF members have also acquired some and voice accolades.
Aside from talking with Dupont the next few steps are; (a) possible California trip, (b) a request to the MoPop to see the phaser (can't hurt to try). Now some pictures (this is all my stuff/my-props):
