Hermann Ratzersdorfer was not mentioned in ``Liste der k.k. Hoflieferanten 1866``.

When was he appointed k.k. lieferant?
Several important enameled pieces sold at auctions had no imperial eagle beside Diana`s head, and that was after Radlpunze.
Gemarkt: Wiener Dianakopf und Windhundpunze, Meistermarke HR für Hermann Ratzersdorfer.
Is this the quality expected by Hermann Ratzersdorfer?
Is this the mark of Imperial eagle?
(Just my opinion, not everything he made was rock crystal and enamel, but still).
I find the marks very spurious,particularly without full sets of marks found elsewhere.
