Brass front helmet plate for Czapka (Tzchapa), Lancer's cap of the British 17th Lancers This badge was sold by Jim Purdy for $160.00 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. Czapka is a Polish and Belarusian generic word for a cap. However, it is perhaps best known to English speakers as a word for the 19th century Polish cavalry headgear, consisting of a high, four-pointed cap with regimental insignia on the front to which feathers or rosettes were sometimes added. The 17th Lancers (Duke of Cambridge's Own) was a cavalry regiment of the British Army, notable for its participation in the Charge of the Light Brigade in the Crimean War. Various amalgamations have resulted in its absorption into the Queen's Royal Lancers (which also incorporates the 5th Lancers, 16th Lancers and 21st Lancers).
