Very little is known of this company other than they were in operation sometime ca 1850s - 1870s and that they were located in the general region of New England, USA. The vast majority of their "silver" items were made of "Coin Silver" (see our Glossary through our EXTRA HELP section), which was typical of that era in America.
Other marks:
a) The chevron mark was used as one of the unofficial hallmarks for Hanau, Germany. You will find this mark in our
database under the "DIAMONDS, TRIANGLES etc" and other Shape Categories, or use our NAME SEARCH for Hanau to see it faster (no. 9 etc on
that list). This indicates that the Case was made in Hanau, Germany. For more on Hanau and Hanau Silversmiths, please see our article on Silver Pseudomarks.
b) The shield with the Crown and the number 18 symbol is a variation of the UK hallmark for 18K Gold ca 1798 - 1974. Please see our
"Recognizing Country Hallmarks" page through our EXTRA HELP section. This shows that the case (and possibly the entire Watch) was imported to the UK after
it was made.
c) The "SF under crown" initials are those of the UK importers that made this watch & case available to the UK market. This mark
refers to SAMUEL FREEMAN from Coventry (near London) who was himself a watch maker ca 1860s - 1890s and probably imported this watch for
resale.
d) The G mark is that of the original maker of this case in Hanau and most likely for GUTGESELL GEBRUDER [means Gutgesell Bros.], who worked around the same time (ca 1860s - 1890s).
Also, if you use our NAME SEARCH for Hong Kong, you should also be able to see several other marks from the region and compare with similar ones in Kanji (simple Chinese) characters.
The BM initials refer to Britannia Metal - please see our Glossary through ourEXTRA HELP section.
