Hi Kallstrom,

Welcome to the Forum,

I can't help with the maker, but look towards Norway as the country of origin.

I finally figured out how to embed the pictures, and I had read one of the newer posts in Other Countries saying that 13 1/3 is more likely to be from Denmark, so could this possibly be from Denmark then also? I was also curious just to expand my knowledge around what time frames were 13 1/3 loth used in Denmark. Thank you

Børs is from Bergen Norway. Dont have my books here,

This is becoming interesting. Yes, Christian Børs was active in Bergen, Norway. He became master 6.9.1814 and worked to 1.8.1859 when he died. He was alderman in the guild 1831-1833.

What is interesting is the silver fineness of 13 1/3. That is not common for Norway but it seems to have been used by some masters. My statement in the other thread was based on information in the newest book of Norwegian silver i.e. "Norsk Sølv, gullsmeder gjennom 600 år" published in 2013. It states "...In the 1800s the silver standard is given in marks such as 12L, 13 1/4 and 13 1/2 and Prøve as in all parts of Norway. " The only cases of a differing standard I managed to find was a few fineness marks of 13 1/3.
Can anybody provide more information regarding the use of this 13 1/3 fineness in Norway?

Thank you for all the information, I will have to check out the info in the book you listed, the only other example I could find for a maker from Norway at 13 1/3 loth around the same time period also from Bergen was Andreas Johan Soelberg, pictures are no longer good but here was the original post. viewtopic.php?t=4960
Thanks again everyone for the all the information.
