In October 2016 Ebay seller bmw10_de from St. Wendel in Germany was selling this Bahrain plate.
It is a manufacturer’s sample or rejected test design and has come straight from the back door of the manufacturer. It has never been near Bahrain.
All genuine Bahraini plates of this series are blue on white and never black.
Check what you are buying. Just because you think it looks good does not make it a good, genuine plate.
