As stated on the notes, the Bahraini notes were issued first by the Bahrain Currency Board (Can't find a wiki articel about it), from 1965 to 1973.
In 1973 the Bahrain Monetary Agency took over the issuing of paper money. They changed name in 2006 to the Central Bank of Bahrain (which already exist in the catalog).
Could we add these? Thanks :D
