I have a early 1941 LB and a very early Savage 1942, No.4 Mk.1 (not Mk.1*) both have the Button Style cocking pieces. I have two very early 1941 BSA (Shirley) rifles (first run no prefix letter) both have the slab type cocking pieces. I don't think I have ever seen an early Brit built No.4 Mk.1 with the button cocking piece. Were they ever used in production rifles at the English factories ? As an aside, the LB and Savage mentioned above both have South African property marks and are in excellent ++ condition.
