Price's Grammar School Fareham CCF K&K 2645 wore the lion badge with school founding dates as shown in the photo linked to below. The School did not have an OTC.
The Cadet Corps orginally wore the 6th Hampshires cap badge: From the CCF website: 'A dark blue beret bore various cap badges: the 6th Hampshire Regt. (Duke of Connaught’s Own) until 1938, followed by a Royal Artillery badge until 1945, then the Royal Hampshire Regt 1945-55 at which time the Price’s Lion cap badge was introduced.'
The lion cap badge is therefore a post-war CCF badge and dated to 1955 until the closure of the CCF circa 1975.
