The maker is the mentioned Jørgensen, but is it silver is another question. There is not a single Norwegian silver mark on it indicating that (or not showed). Unfortunately Norwegian silver marking procedures are sometimes deficient. Could be or not who knows? I have some doubts...likely plated.
::::: I can dig out a few spoons with 13-1/4 marked on them with a maker's mark, and sometimes even the 13-1/4 is omitted with only a maker's mark stamped on the spoon (Provincial Denmark Silver) :::::::: Not sure what else is supposed to be stamped on this spoon? :::::::::
Norwegian silver was from 1608 stamped with 13 ½ lodd (by law, Christian IV), who is equivalent to 843 S (843/1000). In the 1800´s it was permitted to stamp silver with 13 ¼ lodd. 13 ¼ is equivalent to 830 S. When Norway switched to decimal system in c. 1892, the 830 S (minimum standard), and 925 S stamps became the new standard. So in other words, your spoon is in silver! Stamped with maker´s mark O.C. Jørgensen, and the city stamp of Drammen.
::: A combination of stamping issues (weak strike when actually struck and/or crude construction of the 13-1/4 on the punch itself) and digital-camera-software pixel-stacking :::::: The image that you see has been translated into pixels by the digital camera software, and sometimes there are issues with the pixel-stacking process, that's why it's always best to have the object in hand and turn it slightly under a light source ::::::::
::::: My brain has seen the "13-1/4" stamp before on Norwegian silver so my brain interpreted the image as "13-1/4" almost immediately :::::
Hi,
Irrespective of what have been "explained" here I am still rather skeptical like Traintime. I don't either see any 13¼ but a rather clear 13Z. Moreover, Oluf Christian Jørgensen stamped O.C.JORGENSEN or simply O.C.J..I cannot see any O to the far left in the name punch. There is some other letter. In addition Jørgensen's whole family name punch doesn't either show a Norwegian capital Ø like here but a capital O. The punch "PRÖVE" (test) is also missing.Take a new look at the picture on 3.7. I still stick to my first answer.. All in all a rather strange marking on a Norwegian SILVER spoon. On more thing, if the fineness would be 13¼ no slash would have been used but a hyphen minus (-) in the punch.
