it has no aperture blades, always open. It belongs to the night vision NZT-1. Nice alternative to Helios-40, cheaper, but not that easy to find. There were many of them 10 years ago in Germany, probably the old Soviet Army staff.
Ah, I see. Thanks for the info. Sorry it's taken me so long to reply, but I've been trying to find various bits and bags for my 7 cameras and running films through some of them to test them.
