I can't be alone here. What unusual things have you come across hidden in wall, attics etc?
I once, tucked away in an attic, found a hollowed out African Elephant's Foot. The work was obviously done by a taxidermist.
The homeowner had lived there 20 years, and never knew it was up there.
Another time, during the demo of a wall, I found an RG 22 (read cheap) revolver wrapped up in a shop rag. The frame was made of diecast zinc, and the cylinder to barrel gap was so big that it sprayed as much lead out of it as at the target.
