Ludwig introduced the new Stipelgold finish in their 1926 catalog. “The New Ludwig “STIPELGOLD” finish is a special composition producing a marvelous *“Stippled” effect in a bright golden hue. It is hard and durable, adhering tenaciously to the shell of metal or of wood.” The 1927 catalog introduces the “New Ludwigold Iridescent Display Finish”. It looks like the Stipelgold finish was short-lived, maybe 1-2 years.  Aside from the 1926 catalog, the only other reference to the Stipelgold finish is at the bottom of the first page of the 1927 catalog: “LUDWIGOLD or STIPELGOLD at the same price.” So as best as I can tell by researching the 1926, 1927 catalogs and Rob Cook’s DRUM COLORS THE REBEATS COLOR SWATCH BOOK; Stipelgold was only around for one year, 1926.
