HC Deb 08 June 1943 vol 390 c553W
Mr. Bellenger

asked the Secretary of State for War whether officers and other ranks are permitted to wear any indication of private mourning on their uniform?

Sir J. Grigg

Yes, Sir. King's Regulations, 1940, paragraph 1010(b) lays down that officers, warrant officers, non-commissioned officers or men may, in private mourning, wear a mourning band of black material should they wish to do so.
