[Hallicrafters] HT-37 Weird Find In Cabinet

[Gary]

I picked up an HT-37 at a local auction this morning for $10.00. Set it on 
the bench and took it out of the cabinet. First thing I noticed was MONEY. 
Yes, it was a two dollar silver certificate. Why this was in there was 
beyond me until I noticed the cover was missing from the relay. Back when, 
we use to burnish relay contacts with a dollar bill. I guess this is why the 
two dollar bill was there.
    OK, what kind of weird stuff have you found inside of a radio?????
