Hello, just offering a possibility, but "0.800" rather than "800" can also be found on Swiss pieces. To my knowledge designer's monograms or names are never to be found on Hanau-like pieces like that, so I rather suspect a retailer, too. Regards Bahner

Hello, A. Wieder was a retailer/seller from Cologne/Germany, later from Stade. He mostly sold patterns designed and made by major German cutlery manufacturers, in this case a pattern by Koch and Bergfeld from Bremen, one of the patterns attributed to designer Hugo Leven. Lehn went broke in the 1950i...

Hello, crown and halfmoon may vary, their shape rarely give good clues. Would agree that POSEN and the P were added later, the other marks are in my opinion those of the original maker. Regards, Bahner

Hello, a closer look reveals that the P in a shield was punched over another mark, tend to believe it was the Bruckmann eagle. Posen retailed a LOT of Bruckmann holloware and flatware. Though Posen had its own workshop at least until the end of the 19th century (even the name of the chief designer t...

Hello, B would be the mark of the second warden Deppe 1842-1847, V. might be maker Vollgold. Regards, Bahner

Hello, in many cases a German city mark would also guarantee a certain minimum fineness, so an additional mark would not be necessary. This was the case in Hamburg and Altona, believe the minimum standard was 12 Lot / 750 fine. 800 was very uncommon before 1884. Regards, Bahner

Hello, most likely an internal production number of the maker. It will be near to impossible to find out its significance. Regards, Bahner

Hello, no doubt that the 13 is for Lot. Also agree that this is not Bibus but older. Unfortunately it will be near to impossilble to identify the maker. The pattern was VERY popular across Europe and without any other clue... Sorry. Regards Bahner

Hello, believe we need better closeups of the marks. Cleaning them before making another shot may do the trick. Regards, Bahner

Hello, not sure what you want to know, but this reads Bruglocher, one from the Bruglocher family from Augsburg. Most likely J.J. Bruglocher, died before 1846. Best wishes, Bahner

Hello, most likely marks of Wolfers from Brussels for the German market. Regards, Bahner

Hello, this is the mark of the Saxonian company Langer & Günther. Regards, Bahner

Hello, this is just another mark used by the company. Regards, Bahner

Hello, this is not a maker's mark, but a former owner's or donor's monogram. Is it possible that the 75 is actually an incompletely struck 750 ? Regards, Bahner

Hello, Carl Stabenow was and still is a jeweller from Stralsund, Germany.

The logo on the top side of the piece may have some connection to that region. From my experience the current owners have little to no knowledge of the back history of their company,. Regards, Bahner

Hello, rooster - seriously ? I must say... This is of course the Berlin bear with a letter for the first warden and the B of the the second warden. Wilm would be the famous Berlin family of jewellers, gold- and silversmiths. Regards from Berlin, Bahner

Hello, absolutely, this is a/M for Hanau am Main. Regards, Bahner

Hello, looks to me like a (German ? Dutch ?) tea caddy in the traditional "Frisia" pattern. Best wishes, Bahner

Hello, this is not silver but pewter, 95 % as the mark indicates, the rest being some other metal. Maker is Frieling, one of the many German pewter makers of his time. This dates very roughly around 1960-1980. Regards Bahner

Hello, the old fomula used nitric acid and potassium bichromate (both hazardous) in distilled water. If you get access to these chemicals you may find short films on the internet on how to make the testing solution, which runs under the name of "Schwerter's solution". Be extremely careful ...
