I bought these separately from Ukrainian sellers. The Zorki C was priced at BP 10.xx. The seller said that all parts were in tact but the shutter was mal-functioning. He would not give anymore details. So I took a gamble and bought it. The usual CLA made it work fine. The lens was priced low; I bought two of them for BP 1.00 each. The seller described them as “bad…and full of cleaning marks.” I found them very badly neglected. The Aluminium had become dark gray due to weathering. Luckily there was no fungus. The cleaning marks were not scratches but looked like dried up soap or detergent. It look a good CLA and polishing the barrel. I removed the old green grease and lubed the helical with new AP3 front-end grease. Both body and lens seem to have been stored badly, but rarely used. I walked around the neighborhood today for some test pictures. I used Ultrafine 100 film and home brew.
