This phaser puzzles me. Never mind the excellent condition--the acrylic meter cover is yellowed with age, but not the emitter? Why? If it's real, how does that happen? If it's fake, how did the forger miss that obvious detail?
It's not real.
As for the discrepancy:
I should reiterate (without getting into specifics) that, back during the "hero" auction debacle, I was made privy to several inside documents from the auction. There were a number of big red flags in the provenance, and one key bit of info seemed like it was included as an in-joke by someone with a massive ego, who wanted to "sign" their fraudulent work. They clearly thought that no one but a hard-core STAR TREK fan would catch this reference, so they snuck it in to be "clever".
I have absolutely no doubt that the same parties are also responsible for THIS forgery. We all knew they'd strike again after the last auction was successful, and now they have. And I'm sure that the YouTube video of the late Ms. Nichols showing off "her" fake props was removed to help hide the trail leading back to the guilty parties.
But there are still enough dots out there for people to connect, even if I personally can't do it publicly. Believe me, guys, I'd LOVE to tell you the whole story. You wouldn't believe it. But I gave my word to several independent sources that I wouldn't. And it burns me.
Anyway, Ms. Nichols was suffering from cognitive issues near the end of her life, and she was roped into more than one dubious fan-made project designed to make money from her endorsement, like that crowdfunder to rebuild the TMP Enterprise FX model. I wouldn't be surprised to find out that she was taken advantage of, here.
Again, I can't go into detail, but the "hero" phaser auction made use of an elderly (and possibly cognitively-impaired) TOS guest-star to establish "provenance". But the signature on the Letter of Authenticity looked falsified to both myself and one of my sources. Like someone found a copy of the person's signature online and digitally pasted it in. There was visible artifacting around it. The guest-star in question may not even have been involved at all, with merely their stolen signature used to falsify the provenance.
That's the level of what we're dealing with, here, people. As well as bribery and corruption within the auction house, in the case of the "hero" auction.
Everything is rotten in Denmark, and it sickens me.
