I don't think they used a lathe for that...

The nose cap pictured in post #19 doesn't look renumbered to me. It looks like the original machine marks on the bayonet boss.

I think so BAR but the nose cap has been mounted eccentrically. Same as the manufacture of the nose caps on Sterling SMG's was machined.

Look like milling (end mill) to me.
