GERMAN PORCELAIN MARK IDENTIFICATION
I tried to research the trademark "S" on the back with Germany written inside the letter, but, did not come up with any information on eBay, Kovel or Replacements.com. If anyone knows who made these plates I would really like to have you contact me so I would have a little more information. This mark was used by K. Steinmann (Kuno Steinmann) between 1900-1932 or 1938.
