If it were her, Norman, I"d be expecting a full signature, and if only initialled, with the initials in the reverse order. (KM, though one early piece is known with MK, but that dates to the 1950s) Nor, it has to be said, is the decor stylistically typical of her work, usually very fine and complex, line engraving. Is it sand or bead-blasted decoration, or etched? It seems very crude, using a simple resist technique, but what appears to be a Czech blank, was used. Unless Jindrich thinks otherwise, I would not get too excited.
