On known objects made by Johannes ten Stall, it shows his maker's mark
ITS is under a comb. This suggests that the maker's mark a
comb in a shield should be sought in Ten Stall's family. Johannes had no sons or brothers who were also silversmiths, ergo family members are not eligible. Indeed his father-in-law was a silversmith, using
TVL as his maker's mark. Of course, there is still the possibility that a master, without any ties to the family
ten Stall, has used the maker’s mark a comb in a shield. Verification is a problem because the copper mark plate (insculpatieplaat) of Utrecht's silver & gold guild, years 1670-1710 with the names of the silversmiths and their maker’s mark has not been saved.
NB. Johannes ten Stall made mainly Roman Catholic ecclesiastical silver.
