The original Stockel is in Danish, The New Stockel is in German. I have both of them so if you can give me a name or some names, I'll be glad to look them up. Also, keep in mind that Stockel isn't absolutely reliable, at least regarding dates. He probably recorded names and marks correctly but often the dates are based on whatever was believed the date of a particular piece was. The result was even more erratic than current dating problems often are because much less was known about the artifacts. That said, in at least one important case I have been able to confirm Stockel is correct in an important date that is otherwise unverified. We don't know what sources Stockel himself used but the original two volumes were published in 1938 and 1943. Eugene Heer simply added to Stockel by raiding Gardner, Carey, Kaufman and all the other published lists. So...any mistakes those works included are included in the New Stockel,
