Thank you Alexander! I can not be sure of cause, but I believe that camera sold on the Photographica auction in Frankfurt was repainted( I do not want use word fake ). If you see in the catalog real black Leningrad has 2 screw design, bottom plate is chrome, and it has other differences. In Frankfurt auction was sold later version of the Leningrad. Plus IMHO paint is to good looking for 55 years old camera, specially compare with not so good conditions of the handles and other parts. And as you mention already the lens wrong as well. I hope that it was sold for reasonable price for fantasy cameras.
