There seems to be a lot of confusion in this thread of what these rifles actually are.
These rifles are a sporting rifle made up of left over parts at the end of WW2/early post-war.
At the end of the war Long Branch had left over actions and components from the (LB's losing entry in the) lightweight rifle competition (the winning entry was put into production [only in the UK] as the No5MkI).
These left over (non standard) components were assembled as sporting rifles (probably by the tool room or model shop) and presented or sold to "deserving" big wigs and possibly others.
The CWA device on the side of the receiver is the marking of the "War Assets Corporation". War Assets Corp. was a (Government of Canada owned) "Crown Corporation" set up at the end of WW2 to dispose of Surplus goods and materials. WAC survived into at least the 1970s.
