If someone is looking to double their money contact this guy. According to him you can buy his 39 for $4,200 then double your money by reselling for $8,400, right? Even if we went the other way, selling it for half, $2,100 I don't think it would sell. He's also not sure if it's a 50's or 60's machine but he knows what it is worth. Remember, money talks, his BS walks.
