German Cow Creamer hallmarks need identified

[tuarchives]

From this website I have found that the center hallmark (13) is an assay mark for silver purity found on German and Polish silver of the 18th and 19th centuries. 13 = .812.

Does anyone know what the first and third hallmarks are? The first one appears to be "JI" over a larger "S" and the third is a bunch of grapes.

Hello, Your post includes links for two rows of different marks. Supposed that the two are actually to be found on one piece, they seem to point at a more recent Hanau product, regardless of the "13". The grape and the "Gebr. N." point at maker Gebrüder Neumann, founded in 1926. The "JBS" (or maybe "JLS" ?) could stand for Schlingloff from Hanau. If the Durch marks are genuine I cannot say. Best wishes, Bahner

Sorry about the confusion regarding the photos. Only the two photos that you see on this post are for this post. The other two photos that you see when you go to PutFile are for a different cow creamer I have posted in the Dutch Silver forum.

Thanks for the suggestion on Hanau and Shlingloff. I'll research those to see if I can match hallmarks.
