Sony WM-F30 Walkman Black Cassette Player Working - Rare Variation

Description

Up for sale is an original Sony WM-F30 Sony Walkman.
The unit is in excellent condition and looks as good now as it did back in 1984. It has no visible wear or tear on the unit, includes the original case (worth mentioning that there is a slight tear in the plastic of the case as shown in the pictures), and most importantly, still works!
It's very difficult to find these in working order, and this particular unit seems to be a rare variation. Every other WM-F30 I've seen for sale mentions TV audio in the top right, while this one simply has "Dolby Digital" displayed in the corner. I've never seen one like this and I believe it to be a rare variation, or maybe an early first generation model?
The pictures are of the actual item, so what you see is what you get.
I've set the buy it now to a high price to reflect the rarity but I'm open to offers.
Item will be shipped securely in a strong box with plenty of bubble wrap/soft filler.
Thanks for checking out my listing!
