Not exactly amateur radio...
A few years ago I ran across a Ramsey Aircraft Receiver kit that hadn't been assembled. It had been opened and a quick scan showed that most of the parts were there, with a few minor parts missing (labels, jacks, knobs and the odd cap or resistor). Anyway, it was cheap enough, so I took a chance, brought it home and assembled it. It works well enough, but you have to be very patient with its tuning. I live near a busy airport, so I generally just leave it tuned to their frequency and occasionally listen to their comings and goings.
One of it's lid flipped...
and of the back panel...
