Many appraisers have inspected but none have identified. Stamped under glaze with two swords with rounded pommels and letters or numbers in each cross section. 25cm². Messien expert in New York wasn't sure due to stamp not being done in cobalt blue. But majority of those who have inspected claim mid 18th century. Please help.
