The following pennant numbers have been taken from BR 619(2) Distinguishing Pennants and Signal Letters of H.M. Ships, R.F.As., M.F.As., etc, 3 Letter International Calls Signs, Coastguard Stations etc. This publication was issued in 1944 and contains amendments/corrections up to January 1948. Sadly this publication is in a very poor state negating the ability to scan its pages. Therefore all the pennant numbers have been typed. The publication contains many hand written corrections and to maintain a completeness of its entries all original entries as well as all amendments have been included and this explains why you may see two different vessel for the same pennant number.
