Got this beauty today for $20. Looks identical to Hemingway's in the Key West house, but "Aristocrat" instead of QDL (which TWDB seems to say was a mid-year model name change). Really excited about it; all this paint etc looks to be original, and is only worn where your hand has to touch the ribbon cover on carriage returen because of how small it is, which is really moving to me, connection to the past etc.The serial # has a "B" prefix, which TWDB confirms was a thing in these years; does it designate the tiny typeface? Sorry for faint ribbon, but you see--so tiny. Aristocratic?
