These are photos of Russian made manufacturer’s sample plates. Obviously the Russian plate company (Byborg – an Utsch associate company) was trying to persuade the Russian authorities that something more interesting was required for the expected eventual change to 4 serial numerals (or letters) that Russia will require fairly soon. I think the top one looks best.
These plates are probably not in collector’s hands and probably will never be seen outside Russia, but you never know.
These photos are from the Russian language plate forums – see my home page for details.
