Any information regarding this bowl appreciated

[Knorrepoes]

I inherited this small greenish bowl, diameter approx 18 cm. Obtained in the 1960 by my father from an antique dealer. But I have no idea how old it is, where it is from and if it is genuine.

Can anybody help ?

Closeup picture of foot rim, please. Partial is fine. Also a picture of the entire base. Any deficiencies or blemishes/scratches should be visible.

Here the footrim. Whole base I do not have a picture from (I do not have it here), but there are no scratches, cracks or chips.

Probably a 20th century product. The foot rim does not look as if it were official ware, but it looks too pristine for an antique from a private kiln.
