Here's one for the Longbranch gurus. The wartime S.A.L operations at Longbranch were terminated at the end of 1945 to be replaced by the post-war C.A.L organization in the Longbranch plant. What's the best read on when C.A.L started producing No4 components with the C.A.L markings? I've owned 1950 vintage No4s with a mix of C.A.L and S.A.L marked parts and am wondering if there is a consensus on when the C.A.L markings started to appear, specifically if they are seen on rifles which were overhauled at Longbranch during the 1945-1950 period.
