If it is a British gun then it as Raimey says. However if it is an older German gun the mark could be the Vorratszeichen from Germany - the mark put on guns already in inventory when the German Proofs first began in 1891.

Sorry, didn't see the earlier post showing it to be a British gun. This Crown V is a London Proof.
