I do not expect to find any more like them...but then, I never expected to find them either. They were both gifts from the Lord, and I give him total credit for them. The Mac does work(I did check it), and the Marantz appears to work, but needs a couple of tubes. (It will get them before I sell it). In vintage audio, as long as an item is complete and intact and in good condition, it is common to sell them as "original", possibly needing some "restoration", by the buyer. This is fine as long as someone does NOT mis-represent an item as "completely redone", when it has not been. Needless to say, "restored" items command the highest prices, but "as found" ones still go for much $ if they are sought after.
Unfortunately, there are those individuals that attempt to sell items as working, tested and/or restroed, when they in fact, have not been , are non-functional, or even worse, they ues someone else's pictures to sell their item, to make it appear better than it is. This is FLAT-OUT dishonesty, and just breeds distrust and ill will among people. In short--it is NOT smart to try and "go for the quick buck", by falsely stating things, and end up hurting ones self in the "long run".
As for Lawn mowers. a few years ago, we had 2,(one self-propelled and one rider) needing some repairs(and someone with some knowledge could no doubt have made them nice again) , and I just sat them out for the trash, a few days early, expecting them not to be there long.Some guy came and got both of them!!
Blah de blah blah blah.
