Maybe »Hanau« Pseudomarks? Or Amsterdam’se?
Hello Kasper
It seems to be that the salt could be more be made in XX century, then French second half XVIII century. Please look here - »Unattributed Pseudo-Marks on Hanau Style Silver« (lower third of the “page", right side column):
http://www.925-1000.com/Fgerman_hanau_marks_01.html In
K.A. Citroen book »
Valse Zilvermerken in Nederland«
(edition 1977, p. 39, numb. 275) is also shown a nearly similar »
R« crowned; but the
cartouche is slightly different too. The explanation there fore is: »
275 nabootsing van een [French]
jaarletter [it was observed by K.A. Citroen on]
kannen, speelgoed (A)« [
A = on articles from
Amsterdam]. (
Translation: »[number]
275 is a Pseudo French year letter; it was found on jugs and toys.)
The flask like »
bottle«
isn’t mentioned — not in »
925-1000«, but also not in
Citroen.
Kind regards silverport
