I was searching about this camera and saw a post by a photographer from Taiwan (I guess). The photos below were produced by this photographer (Losanfo) using his/her ikoflex IIa late versions.
Below is a image of his camera.
A pretty interesting camera using a tessar lens made by zeiss. Its value is increasing very fast recently.
