Leica bellows 16588 with adjustable lens adapter
Honestly, we do not exactly know what this bellows combination was meant to do. The bellows are numbered Leitz 16588 and they are in reasonably good condition; rail runs smootly. As far as we can tell it is light proof.
The attachment has an adjustable lens opening with a hole on one side and a focusing screen on the other side with a little hole in it. The meaning behind this? Who knows…!
