Even if he COULD remember that period, it's highly unlikely he'd remember that guitar. I highly doubt that's ever even been in the same zip code as Pat T. He's gone on record stating that he loathes Floyds, despite Pat Thrall being an early user.
But by all means, Mr. Seller...just go with your unsubstantiated B.S. Funny how when this exact guitar was for sale less than a year ago, there was zero mention about Pat.
