Untested. Came from an estate sale. 

Minor scratches. Shutter and release work. Release is marked made in Switzerland. 

Not sure exactly what this is called.  Has a lens out to the side that looks out the front with a dial that has a + 0 -. Then a dial on the side of the shutter T B 125 50 25 10 5 2 1. I think its a timer.

If anyone can tell me what this is call please let me know via e-mail. Thanks in advance for any information.
