I lived in Central Pennsylvania 1990-1995 and visited craft fairs and shows.
Once I saw what appeared to be a normal 8X10 picture, but it was actually a place (box) to store items some what secretively in the wall. It was less than 3 " deep, framed of wood and mounted between studs. It was simply a "picture on the wall" from looks.
Specifically, this "model" allowed a pistol to be stored in the wall behind the "picture" and accessed when the "frame" was pulled open like a medicine cabinet. What I like was that with the cabinet open the gun handle was easily reachable. The gun barrel was simply positioned over an (angled/diagonal) brass rod (round and prevented barrel damage?) that swung out. This piece was also a part of the frame/hinge....
If anyone can help, it is appreciated. I don't know what it was called as this was years ago and I would love to make one now (DIY).
Thanks.
