On a point of interest (I am not suggesting the vase in question is from either of these makers) the classical frieze style of vase was copied in pressed glass by Rindskopf in Czechoslovakia and Riihimaki in Finland. Both of them made iridised versions of these items, with a decorative frieze that features classical figures.
Rindskopf's were unusual in that they actually used a verdigris sort of stain that gave an oxidised metallic affect to the pattern frieze. Riihimaki simply used a frieze featuring moulded classical figures (female) - in a total "rip-off" of the Moser version. They're fabulous items - the Riihimaki examples are rare as hen's teeth; the Rindskopf ones are more available but still hard to find.
