Exactly: the second standard (.833) lion and (close!) the year letter “W” for 1831.
The maker’s mark is that of Hermannus Ridder (later Weduwe [Widow] Hermannus Ridder), working in Groningen 1812-1859. (This mark, however, was used only 1830-1833.) Also, I think I can make out the letter “E” in Minerva’s helmet, which was the letter for the Groningen assay office.
Hope this helps!
