L42a1

I would say your L42 rifle doesn't have Chordal Rifling, and here's why.

A limited number of L1A1 rifle barrels were made c1975 with RSAF designed Chordal Rifling, each barrel was marked to indicate it was one of these special barrels because the rifling is so radically different.

According to SM&MG D119 Misc Instr No. 30, dated Dec 1975;
...The Chordal rifle barrels are identified by the letters 'CB' engraved on the reinforce that provides location for the sling swivel and this marking can be seen without the need to remove the handguard... .

This tells me that if any other weapons were fitted with barrels with Chordal Rifling then they too would be marked in the same way as indicated for L1A1 barrels with 'CB' engraved in a place that would be visible without having to remove anything from the rifle. Does your rifle have 'CB' engraved on a visible place on the barrel?

BUT the biggest give away that your rifle doesn't have Chordal Rifling, is that your rifling doesn't match the diagram below which clearly shows the vast difference between Standard Rifling and Chrodal Rifling.
