So, I bought a really nice bowl the other day. It was in great condition, and the mark tells me it's by Zeh, Scherzer, & Co. Made between 1880 and 1910. I paid $21, so I hope I didn't overpay. I am wondering who the signature is from, though. I think it says Croquer or Croquier.
I've added 2 photos. If anyone wants a photo of the mark, I can post it too.
