TS, I reckon all of those Omegas are re-dials (bar the Railmaster, of course).
Just be careful of where it's been. In India they cobble together frankenwatches, and that's often where they get re-dialled.
Black dials are usually gloss, apart from original military issue dials. The Seamster 600 (the one with triangular markers) was sold in large numbers with a black dial, but even that one is often re-dialled.
