I think there are a couple of threads at the moment that show the difficulty of obtaining information on badges worn by early cadet units ( indeed it is difficult to obtain information on badges worn by some cadets in the fairly recent past )
I cannot remember where the notes below ( which were made in 1952 ) came from but they do show an incredibly rare Liverpool Cadet badge which I have never seen an actual example of, it does show where the design of the Liverpool College OTC/CCF badge originates from and does at least show another item to be looking out for.
P.B.
