I have one Zenit 18 body with a little problem: One of the 2 battery door on the baseplate is missing and the screw of this door is broken in the baseplate. I have 2 options: If someone here has a complete base plate for Zenit 18 to sell, I will be very happy to buy it at a price that makes seller and buyer happy. If not , I have to find a battery door for Zenit 19 with screw (Zenit 19 battery door is the same but there is only one). I will just have to find how to remove the part of scerw remaining in the baseplate of my camera. I think it is possible. I can also buy a faultly Zenit 19 if this camera is complete, especially baseplate...
