Many people actually believe that H03VH-H is no longer legal for mains voltage and in DIY stores it's usually labelled "42 V max." although at a closer look the original 300 V marking is still there. I don't think equipment manufacturers ever used it since the 70s, the Italians probably kept it around a bit longer than the others (e.g. on table lamps) but that's it. Austrian and German H03VH-H has unmarked conductors as far as I know. I occasionally use it for nostalgia's sake but that's about it.
Most Schuko plugs aren't designed for H03VVH2-F or the likes either so I usually fold back the outer sheath to provide a better grip. On some plugs you can flip the cord grip and turn the convex side towards the cord, gripping even very thin cords.
