Mortar and pestle (2) - Brass, Bronze - Stamp marks

Antique metal mortar with knob handles, pestle, and maker’s marks – probably 18th century

Cast mortar with two spherical knob handles and a matching pestle. Several rectangular maker’s marks are visible on both sides of the pestle; the characters are difficult to read due to wear, and their meaning is unknown. The metal appears to be a copper alloy; it cannot be determined with certainty whether it is bronze or brass. The exact origin and date have not been confirmed.

Pestle length: 9.5 cm
Pestle weight: 65 grams

With greenish-brown patina, signs of use, and discoloration on the base and interior. Please see the photos to form your own impression of its condition.
