I have acquired a handbearing compass which to all intents and purpposes is a type 06 but all that is written on it is patt31 and a serial number. anyone an ideas?

WW2 air ministry hand held compass in its wooden box PATT 31 • £41.00
Patt 31 is possibly an abbreviation of pattern 31. See here: HMS Tarantula, river gunboat - British warships of World War 1

Thanks for info. Mine has a black compass card and no letter after ser# which indicates maker I believe.

Google Henry Brown and Sons or Sestrel Compass. There's a good chance it's one of theirs

I have tried both and got nowhere. compassipedia has nothing either.
