British “Coldstream Guards” enlisted man’s cap
The Coldstream Guards is one of the oldest of the five “household guards” regiments. Formed in 1650 under Colonel George Monck, the regiment takes its name from the town of Coldstream on the Tweed, to which the regimental headquarters moved in 1659, the year after Monck was appointed General Commander in Scotland after the death of Oliver Cromwell. The regiment has been involved in virtually every major conflict, up to and including the Gulf War and peacekeeping in Yugoslavia. Many thanks to Phil for sending this one to me.
