I have never seen this knifes with soldiers on it. But this one looks like an exception. Wonderful, however it only marked with a makersmark that I do not recognize. So I need some help to determine this knife. Thanks in advance!
This knife attributed to Voet nr. 522: Bernardus Johannes Jelgerhuis, who (already) became a master at the age of twenty in 1779. He was the third generation in his family, after his father Johannes and his grandfather Bernardus sr. Junior did not grow old: 1759-1805. Apparently he no longer lived in Leeuwarden in recent years but in Rijperkerk/Ryptsjerk, where his father had also lived and died. That may also have led to the fact that no work was known by Bernardus jr. - until the discovery of this knife.
According to K.A. Citroen in Dutch silversmiths marks and names prior to 1812. Bernardus Jelgerhuis II, was registered in Leeuwarden with a letter mark BI executed in italics, 1779-1802.
Bernardus was born in Leeuwarden, Friesland.
Baptized on March 21, 1759 in Leeuwarden. He died in the year 1805
Father: Johannes Jelgerhuis
Mother: Grietie van Sippama
Special features: Bernardus van Jelgerhuis;
buys Sipmastate in Rijperkerk in 1805 and also lives there, sells (widow?)1807 The mark on knife
The mark as shown by Elias Voet Jr. Merken van Friesche Goud-en zilversmeden published 1932
The mark as shown by Elias Voet Jr. Merken van Friese Goud-en zilversmeden publised 1974
NB. Gildebord van zilvergilde or silversmiths' guild board
We see no representation of this form in that good old Voet of 1974. a master of whom only a stylized board version is known in Voet. So someone whose work was unknown. In my opinion, this mark most resembles B.J., where the flag of the J flutters emphatically over the letter combination.
I don't think so, it's not plausible to me. The mark is BI in italics, not con-joined. If you see it as possible, you cannot attribute it, but at most mention it.
As you say yourself, you don't come across a Dutch silver knife handle with the image of soldiers, so perhaps not Dutch but Continental or with a fantasy mark.
