This is just something i took in on a trade and have no use for and very little knowledge of. It does show some signifigant wear and signs of previous use. From what i understand, this model was released in the early 80's and retailed for about $1,200. I would imagine any potential buyer of an item like this would be a collector or enthusiast and be fully aware of what is being offered and any potential restorations, cleanings, upgrades, etc that may or may not be necessary. Please understand i know pretty much nothing about high end vintage cameras. There is an entire wikipedia page about this model and its variants so if you have questions thats probably a good place to start. Ill assist in any way i can but again, my knowledge is very limited.
