Dear Sebastian
To answer your question: "Was just the maker's mark sufficient guarantee of fineness in mid-19th century Switzerland?"
In very short: yes!
A little longer: There is not yet a lot done concerning 19th century Swiss silver. An exception is the cataloge "Weltliches Silber" from the Swiss national museum. But a few sentences can enlight the situation a bit.
Until the end of the old Swiss Confederation in 1798 all major cities hat very strong guilds. All cities hat a system established to identify the silver and to maintain quality/silver standards. This was usually organized by the guilds, not by the city authorities. Of course this led to many various systems.
In the Napoleonic area the power of the guilds was reduced, and after the restoration of the old order after 1815 they never managed to regain the authority again. Marking systems with at least the manufactures mark and a city mark continued, but it was more a tradition, no law was enforcing the system.
The final decline of the guilds and the regulations was in the 1830ies. The trade was freed and a lot of new silversmith started production.
Before 1830 most silver bears a city mark, which is somehow a guarantee. But the silversmith punched it himself. After 1830/1840 we find a lot of silver only bearing the manufacturer mark. A "13" mark or a city mark are rare. Around 1850 about half of the silver has a fineness mark, usually "13", later "750" or "800". After 1870 virtually all silver bears a fineness mark.
We can conclude we observe a market driven situation. In the 1830 the customers still had the guarantee of a controlled system, later in the 1840ies and 1850ies they had to trust the silversmith. It seems the German example of marking the fineness raised a similar demand in Switzerland.
In 1882 a uniform guarantee system was establised, the grouse mark. But this was not enforced. It seem that the markings in Switzerland after 1840 were mainly a result of the requests from the customers.
Hope that helps
