Low bowl - Carstens Elmshorn, design Siegfried Möller

A low bowl in earthenware (195mm diameter) with incised marks, impressed number plus ink stamp Foreign with a star in blue.







Any thoughts?

Volker (vhb64) may know, he has a similar one as his avatar.

Congrats, i.e. i´m envious. Carstens Elmshorn,  design Siegfried Möller, documented 1932 in an ad, poss. an identical piece  if i recall correctly,  the shape  was quite  successful with Spritzdekors on earthenware with white clay (form 270),  this example marked  K 270  like Keramik or Kunst - Keramik  is very rare,  i´ve seen only 1 example with "K"   before.

Many thanks, Volker. I have had the bowl years but I was never able to find out anything about it. Don't know what I'm going to do with it, that is, if I can find it in my storage boxes.
