Hand stamp with cast metal print plate approximately 8.5 x 6.5cm and wooden handle. It has a large King's crown at the top with A.M. beneath and a stores reference number below ' H/531379/41' (1941). Too large to be a document stamp so presumably used for marking equipment or boxes/crates for equipment. We have never seen anything like it before so it must be rare. A great looking item in very good condition. Stock code M22873-143.
