So was it stolen?
“Went missing” and then wound up in a used gear shop.
The original owner/heirs don’t have a claim to it?

It helped that Lennon had played the guitar roughly, leaving behind marks as he slapped and strummed hard behind the strings. Yet McCaws friend and performing guitarist Marc Intravaia said McCaw paid great care to the guitar, making sure it was never damaged. You cannot have it both ways.

And I think he’d say ‘I knew this guitar would come back now me.’....

What? Is Lennon still doing drugs?
This was shortly after a night of peyote and mescalin bliss during a red moon night in the mountains near Santa Fe. The guitar and I became one. It produced notes never heard before and when I played the notes backward it said:
I am johns.... I am Johns...we are one... and altogether now, I am the eggman... I am the walrus... koo koo ca choo
And after some rube pays half a mill for it, what’s he going to realize? That he paid half a mill for a guitar he could have bought for $300 in any Music store.
I’d let John McCaw sit in a jail cell until he “remembers” who he bought it from. If he can’t, I’d be forced to assume he stole it himself.
“what it meant and could mean to the world.
Sooo like, anything “Beatles” should mean something to the world? Like they were Beyonce’, Justin or somebody kewl like that?
Identified beyond a reasonable doubt?
Just dang. I was in Austin over the weekend and visited the Capitol bldg. Wish I had known of this before. Last time i was at the LBJ museum was 1974 to see Walter Cronkite give a speech, the highlight of which was a "Streaker" running across the stage behind him.
1. How many of this model of guitar were manufactured?
2. How many of those have been played rough in the past 52 years?
3. How do the answers to these two questions prove that this was Lennon’s guitar?
Was there something else found in the process of authentication that isn’t reported here? Because I’m not buying the logic.
I thought all Gibson products have serial numbers. If so, Gibson could confirm this guitar was sold in England.
