He has done these auctions in the past. I think it’s just a rich man’s garage sale.
Exactly. It's an 'auction', not an 'estate liquidation'. He's no doubt accumulated a LOT of gear 'n guns over the decades, and he's at the age where it's time to thin the herd. I'm sure he's still got a core collection that is mind-boggling if he's letting these items go. Ringo Starr had an auction a few years ago and he said it was because he hadn't seen some of the items in 20 years because they were in deep storage.
