Wasn't that 88 which was sold? http://fotobus.msk.ru/vehicle/209247/#n221443

They were both sold by the same time. A couple of days ago, I updated the database...still pending, though.

I also added the VIN, we now only need someone who can verify it ;-)

I do have a screenshot of this bus with those wheel covers by the time it was for sale at:

It is still pending because I am not sure who exactly is that one in Perm: 88 or 90. There are photos of 88 (or maybe 90?) already separated and of rear section already in Perm: http://fotobus.msk.ru/photo/664424/
Don't worry about other your corrections - I am adding them bit by bit :)
