Judging from past sales and other items offered (lots of electronics) the seller is a pawn shop or close enough. My guess is the guy knows enough to know he doesn't know enough to take the cover off anything. The price is interesting.

Perhaps he means he has no control on how you will feel if he lets it go or evacuates it from the auction?

2 Stops? (let me put my specs on)
I see 4 stops. (maybe it's these glasses)
It certainly is an interesting box. A restoration project or a display case item, imho.
