Hmmm .... can't find an image that shows the Unit sign, sorry - the only front on shot credited to 1 Cav has the unit sign in glare and unreadable.
1/19 .... ah, yes, Wiked-pedia have an entry about the unit. Shows how out of date I am .... the last I knew, 1 and 19 were delinked in 1939-40, and later disabanded. Only 1 Bn was re-raised as 1 Commando Coy in the late 50s. Hadn't caught up with the raising of 1/19 in 1970 as a CMF unit (if Wikwed-pedia is to be believed...)
