Well I have now tried 2 Zorki 4s, a 4 and a 4K. One bought from a Ukrainian trader on ebay and one from a Camera Fair in the UK. Both are in the landfill! Crippling seizures, impossible to turn speed dials, film ripping antics and only about 4 pics on a roll of 36 worth even dismissing.
Still, this one came out ok, 4k with a 25mm Snapshot Skopar from Cosina Voigtlander.
