My pleasure. I should mention an error, though. Sittmann did not die in 1831; that was the year he married. He was evidently still alive and working in 1865. Also, there is apparently some confusion about his birth year - he way well have been born in 1800, not 1780. This according to my reference:
Carl-Wilhelm Clasen, Rheinische Silbermarken (Rheinbach-Merzbach: CMZ, 1986), p. 78, maker #219, marks d & e.
My apologies.
