So Peter, are the markings correct for a rifle that would have started as a Mk III then converted to 7.62? Or is the nomenclature slightly off? I can add the painted portion as I have seen many pictures of that marking. Did the painted markings persist through the life of the L4 production, or was it just done to "early guns" until everyone became familiar that this was a "7.62" firearm?

I would have loved to seen this rifle produced in the .280 or something along those lines, like the Venezuelan 7x40. I would have hoped the cartridge would not have been as hard on the working parts?
