Personally I would not unless it was a screaming good deal and the return policy was rock solid. I learned the hard way when I bought an SL66 kits from a guy in the UK (I'm in the US) who similarly to this situation was selling off his late father's kit he found in storage and was not sure how long since it was last used. He said it looked and seemed to work fine, and photos of the camera looked alright. When I got it the musty/moldy smell as I opening the shipping box was my first clue. The camera leather had mildew, the lens had spider-webs of fungus and while the shutter fired it needed some serious work and had pinholes in the curtains. Was not worth the $200 less I paid than if I bought such off a photographer or from a shop with a return policy. Jurgen Kushnik did a decent job on it before he went back to Germany from LA but in the end it was not worth all the trouble as I really go less for more...
