Ex Kay Robertson Collection # 5224 and acquired from Al McGuinness in the late 1960s. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien-Welt" November-December 2017). Probably from the well-known In den Dellen quarries, where collecting is now strictly forbidden. Classic combination material from the locale.
