The spoon is marked with T. Bors (or Börs), 13L6 (13 Lot + 6 Gran = 830/1000) and a small mark with pehaps CG from what I do not know what it means. I suppose the country of origin is Norway. I could not find the maker. 10 years ago Qrt.S wrote about Christian Bors, perhaps the father!?

I found this on digitaltmuseum.no: https://digitaltmuseum.no/021026107020/skje

Børs, Torbjørn Ludvig Synnestvedt (1819 - 1888)
Norge Hordaland Bergen

The first mark could be year, maybe (18)60.

Did I, cannot remember :-)))...Anyway, yes the mentioned T. Børs is the son of Christian Børs (master 1814-1859) in Bergen. Thorbjørn worked in his father's workshop as from 1844. He became master 24.9.1852 and continued in the mentioned workshop to his death 20.8.1888. He was the guild's last alderman (1867-1869). (He took over the workshop after his father's death 1859.) Moreover,
Hordaland was a county, nowadays called Westland. The first mark (60 or 66) is the year 1860 or maybe 1866?

Thanks Sasropakis and Qrt.S for your inputs.
