In both additions, transcriptions and images of the original, you’ll find a letter code that aligns with each service number. This code helps define the serviceman’s role as follows:
F – Fleet Air Arm.
J – Seaman and Communications Branch.
K – Stokers.
L – Officers’ Cooks and Stewards.
M – Miscellaneous.
SS – Short Service, Seamen and Stokers.
SSX – Short Service Seamen.
Pensioners – no prefix.
To search these records, use the advanced search page and filter to series ADM362 for the 1925-1939 additions, or ADM363 for the 1925-1929 additions. They’re a continuation of FMP’s British Royal Navy Seamen 1899-1924 collection, so if your ancestor did join before 1925, you may have already found them here.
