Very B Type differs from regular b type by the shape of the uppermost ridge which is more rectangular in the very b version
These types apply to the 2016 and 2017 cars as well, I talked about this in that section but as a recap for the most part A is located east or south, C is west of Omsk and B/Very B is everywhere west of Irkutsk.
Very B is found in the most locations but A type is the most common due to eastern 2016/2017 being more common than western
For the most part the tilted short antenna follows a diagonal line between Karelia and Volgograd with some random tilted elsewhere in the south (mainly Stavropol) and some in downtown Ufa.

Blurred is mainly Volgograd and Leningrad/Karelia. With some downtown Ufa and Krasnodar
99% of the tilted antenna north west of Moscow is May coverage with the exception of Leningrad.

Short antenna Leningrad is usually tilted with very little straight short antenna (which is A type)
