On the other hand some folk get hold of a rare piece that doesn't look like a radio and sell it as 'unknown scientific item' or such.
Unless experts spot it, it can sell for peanuts.
I have such an item in my collection which was described as unknown.
A PRE broadcast Marconi Scientific Instrument Co., wireless with V24 intact valve which I bought for
a few peanuts. Worth many sacks of peanuts !
