It is a model 3,5 C according to Prochnow, or a 3,5 E according to Parker. Viewing lens is a Heidosmat 1:2,8/75, while the taking lens is a Schneider-Kreuznach XENOTAR 1;3,5/75 mm nr 5393875. Lightmeter reacts to light and gives reasonable readings.
Shutter works fine, Lens glass is clean and clear: no scratches, no haze, no fungus, no separation. I'm sorry but no lens caps or other accessories are available.
