Sony Walkman wm-eq5 cassette player order

Product Name: Sony Walkman wm-eq5 cassette player order
Beautiful but low end product, very unique design ad beans product line, I have little knowledge about it but I did own one similar back in year 2001, fully transparent body style. What's not working : The silver paint faded for the middle chassis order (it's all plastic). Also a rust dot in the metal piece inside (I'll try to remove it later). Function wise , there was a small corrosion inside the batter compartment, which impact the border of circuit board, some green paint came off, but still working. The problem is it's playing one side backward(I believe one of the switch controlling the sound doesn't work, this might be caused by the corrosion I mentioned. The sound is nice and clear though for the other side. this player is quite picky on tapes, I believe it's due to the plastic flywheel , but guess it's not the selling point back then. What's included : player body and original earbuds.
