For a larger version of this model, Kirchner's workbook for February 1733 records '
In der Monath Februar 1733 sind von mir Modelle verfertiget...Eine Bachstelze auf einem Baum sitzend, Lebensgröße...Gottlieb Kirchner' [In the month of February 1733 I completed the following models...a life-sized wagtail seated on a tree...Gottlieb Kirchner].
Carl Albiker notes in
Die Meissner Porzellantiere, p. 120 (cat. no. 33), that work records for May, 1740 show Ehder working on a smaller version. It is possible that the present example could be one of these smaller models.
Sotheby's Scientific Research department used noninvasive XRF for this lot to screen the green enamel for chromium, which was detected.
