Material Ceramic
Mary Walker No. Not listed
Notes There is no knob on the head, which is ususal, and it has a comb at the back of the head.
While it is similar to the Japanese ducks, that is, only the head is different, it is also possibly German given that it has an impressed number on the base, although, this could be an importer's shape number. There isn't any other markings.
There is least one other variant of the usual Japanese shape.
