The style is actually very typical of mid-19th century Dutch silver. The "2" beneath the lion stands for the second silver standard of .833. I detect the tip of a well-worn letter "M" in Perseus' helmet; this the mark of the assay office in Schoonhoven, which was open 1837-1984. ...

Definitely French, with the French first standard (.950) silver "head of Minerva" mark. The maker's mark is that of flatware maker Guillaume Denière fils, dit Deninger (i.e., Guillaume Denière, Jr., known as Deninger) of Paris. This particular mark of his was registered on 16 Dec 1850 an...

Not 100% certain, but I think Seybold & Hirschhauer of Schwäbisch-Gmünd.

Heichrich Haupt of Düsseldorf, listed in 1885, and the mark here registered in 1886 and still in use in 1925.

The top mark - a cursive "V" (on its side in the photo) - is the import duty mark used in the Netherlands 1906-1953. The other two marks - "13" and "N" - are Hanau pseudo marks in...

Not 18th century but 19th, and not Frankfurt but Heilbronn. The Frankfurt eagle generally had the “13” within the mark, not in a separate punch, whereas the Heilbronn eagle was frequently struck incuse, as it is here. And, to my eye, the style of your teapot is very much third quarter 19th century. ...

Definitely Berlin. The letter in the Berlin bear mark was introduced around 1745 and changed with the election of a new guild chief, who served, apparently, an indefinite term. The “K” in your mark was for guild chief/primary assayer J. C. S. Kessner, who served from 19 Jan 1819 to 4 Sep 1854. Unles...
