Vintage Stitz hotshoe light meter in leather case.  This Japanese made meter has been part of my husband’s camera collection for over 50 years.  He thinks it dates from the 1950s.  It I clean and undamaged, as is the leather case.  He doesn’t know the model number as the bottom just carries the Itzuki Inst Co label.  It has been described elsewhere as being a selenium meter, but don’t know if that is correct as my husband says it could be a CdS one. It appears to be able to take direct and incident light readings, using the fold down flap at the front.
