Hi welcome to the forum.
This month I believe you have asked the same question in the ASCAS newsletter # 113 and you should wait to receive your answer next month. But herewith :
Brandy bowl with a full row of Dutch pseudo or fake marks, probably made in the Dutch province of Friesland or Groningen, at the end of the 19th or early 20th century.
Dutch pseudo marks from left to right; crowns in a shield; pseudo city mark of Sneek, lion rampant in a crowned shield; pseudo standard mark used for 1st standard or ‘grote keur’ in the province of Holland, P crowned; pseudo year-letter, crown above an oak leaf: pseudo maker’s mark and last but not least L under a fat dot; pseudo year-letter for the city of Zwolle used 1798.
Please check your brandy bowl for some official (little) Dutch hallmarks, those could be spread over the bowl and hidden in its decoration.
For some information and history about genuine Dutch hallmarks see:
