The marks are pseudo-marks used by the Hanau, Germany firm of Ludwig Neresheimer & Co., which was founded in 1890. I think your cup probably dates from the first quarter of the 20th century.

Ref: W. Scheffler, Goldschmiede Hessens, marks 494, 505 & 518.

Top to bottom, the marks are: 1) a helmeted head (inverted in the photo): the Paris décharge (discharge) mark of tax farmer Henri Clavel for small silver or gold articles in use 13 Jul 1780-31 Aug 1782. 2) "A", crowned: the Paris charge mark of tax farmer Henri Clavel for large silver art...

Bruckmann is the manufacturer, and Sanktjohannser is the retailer (who was located in Munich, if memory serves me.)

See Otto Wolter on this page.

I'm sure Bahner can confirm or expound, but I think it's Oskar Haegele of Schwäbisch-Gmünd.

It's César Tonnelier, working at 7 rue de Cimetière-St.-Nicolas, 1845-1859, and 325 boulevard St.-Martin, 1859-1882. He was succeeded by (his son?) Paul Tonnelier, 1882-1889.

Forgot to mention that it must be a "3" for the third standard of .800; you can tell by the five-lobed outline; the second standard of .900 was a perfect hexagon. In fact, you can always calculate the fineness from the "Dianakopf" outline: a straight line = .150 and a curved line...

Neuwirth's "Lexikon Wiener Gold- und Silberschmiede" identifies the maker as Eduard Tauch, Sr., with no further information.

I think it's a stag, too, but definitely NOT Swedish; the other marks are all wrong for Sweden. Far more likely is the Lower Silesian city of Jelenia Gora, now part of Poland but in the 19th century part of Prussia (and later the German Empire) and known as Hirschberg; see this link.

I'll have to do some digging to see if I can find the maker, but in 1852 the Austrian Imperial assay office code D8 was for the Polish town of Tarnopol, then under Austro-Hungarian control and part of Galicia, and which is now known as Ternopil and is part of the independent Ukraine.

Finland is correct; I believe the city mark is that of Jyväskylä, and the maker A.V.G. is Antti Vihtori Gröndahl, working 1884-1916.

The mark on the left is the trademark of Weinrank & Schmidt of Hanau, Germany, founded in 1889 by Wilhelm Weinrank and Fritz Schmidt. The company existed until around 1970 when it was assumed by the firm of Wilhelm Geist & Sohn. The remaining marks are typical Hanau pseudo-marks.

You're welcome. Do let me know what you find; I think this is a very intriguing set, too. Being a traveling set, I suspect it was made in Mainz in the French style for an occupying French civil servant or officer.

These marks introduced in 1809 were discontinued in 1819, and an entirely different set of marks was used from 1819 to 1838. I think you may have made a typo there. The assay office numbers that Tardy gives are only those in effect for the 1819-1838 marks. Lyon was not numbered 67 until 1819; before...

I can add that the Hamburg city mark with the letter "T" was the mark of assayer A. F. Lammatsch, who served from 1811 to 1828. Laué's death is not recorded, but he either died or retired by 1824, when his seat in the Hamburg guild was succeeded by J. J. Groth. So your sugar box dates som...

Unfortunately, no. Vidal & Moitinho de Almeida (4th edition) is the standard reference; if it isn't there I can't think where to look.

The crowned "P" is Portuguese, the mark of assayer Luís António Rodrigues de Araujo (or one of his subordinates) in the city of Porto. He served from 1843 to 1853, which dates your piece. The maker's mark, unfortunately, is not listed in Vidal & Moitinho de Almeida's Marcas de Contra...

Yes, that's exactly right; it's called a pap boat and is an infant/invalid feeder. You can find more information about them at this link.

Wow! Such a detailed photo demands a detailed response. Mark 1: the assay office mark; A = Amsterdam Mark 2: the mark for first standard (.934) silver, in use 1814-1953 Mark 3: the mark of the firm of A. Bonebakker & Zoon Mark 4: the year letter, Y = 1858 Mark 5: the maker's mark of Pieter Piete...

Gustave Hofer, père (1816-1896) of Lausanne. He was a worker at Frères Gély before opening his own shop in 1846. His son, Gustave fils (1856-1939) continued the firm until 1918. The "2" in the Lausanne city mark refers to the second silver standard, but it is not known if this was .875 ...
