Cap Badge - 18th Queen Mary's Own Royal Hussars This badge was sold by Jim Purdy for $25.00 on e-Bay in the Spring/Summer of 2017. This badge was deemed irrelevant to the museum. The money was used to purchase relevant badges for the collection. The 18th Royal Hussars (Queen Mary's Own) was a cavalry regiment of the British Army, first formed in 1759. It saw service for two centuries, before being amalgamated into the 13th/18th Hussars in 1922.
