434-Ebay leckerzeug2015 cold war military mission fake number license plate
In February 2016 this plate was being offered by Ebay seller leckerzeug2015 from Dusseldorf in Germany.
This is a replica plate made and sold by le_petit_lutin_vert (aka karaya_352) sometime between 2010 and 2012. It is slightly wrong, has never been used and is obviously poorly made as the stickers are starting to come off.
There are more replica and fake (see photo 22 and 23) versions of these cold war military missions (military liaison) in Germany plates in collections than real ones. Real ones are very, very rare and will all have been collected a long time ago.
