Hi Roger, Thank you very much for that, They did come from a Naval source and they are quite rough and are not as smooth as I would expect them to be for drill rounds.
Hi Richard,
They are official British Mk 2 drill rounds, and I have been told that they were used to practice loading the magazines of Oerlikon guns on Royal Navy ships. They were made by lots of firms that had wood-working machinery, so you will find all sorts of different companies initials on them.

Further to the above, these wooden drill rounds were used solely for practice at loading and unloading Oerlikon magazines. They must not be cycled through the gun. If a mag containing these rounds is placed on the gun and the trigger pulled then the breech block smashes into the wood round, rams it very tightly into the chamber and the fixed extractor lip bites a big chunk out of the wood base. This makes work for the Artificer who has to fix the gun and clean all of the wood splinters out. The loading of Oerlikon mags is a bit tricky and needs to be practiced to ensure correct functioning of the gun hence these drill rounds.
