This is a vintage Carl Zeiss Ikon Camera. The condition of the
camera is good with the original cover partially missing and looking its age.
The inner lens states Carl ZeissJena Nr.2286313Tessar 1:3.5 f=10.5cm.
The front of the lens states COMPUR RAPID.
The outer lens states 4296552.
I don’t see any other numbers but it appears the camera is from
around 1937 to the best of my knowledge.
The camera is sold as is. I will try to answer all question and thanks for looking.
