That's a great deal, congratulations! And another wonderfully obscure participant in London's late Victorian pipe trade.
Your pipe was imported and silverwork added by a business started by two brothers, Joseph and Sigmund Suskind (only one "s"), who were originally from Kirchheimbolanden in what was then part of Bavaria. In all available materials (directories, censuses, naturalization papers) they are listed as importers and fancy goods dealers as opposed to manufacturers. As near as I can tell they arrived in London some time in the late 1870s. Styled "Suskind Brothers", the business in its earliest years was located first at 85 Hatton Garden in London (1880), then 33 Hatton Garden (1885) and 12 Edmund Place (1890) before settling at 24 City Road (1900-1910) for the remaining years of its existence.
Joseph (1852-1909) married before emigrating to the UK. HIs wife, Ottilie (1858-1919) was likewise a native of Germany and survived him by about a decade. Together Joseph and Ottilie had three daughters, two of whom survived to maturity. In the 1911 census the widowed Ottilie is listed as being in the fancy goods trade so presumably she continued to operate the business for a few years after her husband died, but she must have sold or shut it fairly quickly since it disappears from city directories by 1915.
Sigmund (1855-1905) married after arriving in London. His wife, Sabine Schwab (1862-1922), was also from Bavaria and together they had one late-life child, Benjamin Emmanuel Suskind (1901-1976). Benjamin was an engineer and uninvolved in the business; hardly surprising since it appears to have dissolved while he was still a child. There are strong indications, by the way, that Sigmund went first to America and became a naturalized citizen here before moving on to London to join his brother.
