I salute to all forum members. I collect Russian cameras since many years. I have 70 cameras in my collection and all the cameras displayed in my showcase work perfectly. I bought the wreck of resament camera ZENIT TL-E and after a week of work, I made all the splendor q'il merit. My camera has the number 770000041. My question is: which lens it was sold? I tentatively put Helios-44-2 Thank you for all information.
