I searched for someone to fix it but it seems there is no one here in Sofia to fix film cameras any more. Well there might be, but I don't know how to find him and I don't feel like searching. So I decided to glue the mada faka the old school way. I focused the viewfinder for my eyesight and then used modeling glue - several drops on the upper half. And it is ok for now but I will see what will happen and write again. The thing I am afraid of is it might affect the way I focus at the lens but I don't think there is any difference in its position of the viewfinder than before. I just have to bring some glue with me when I go outside
I also don't think it will be a problem if I find a better solution to do it but it works for now.
