Ayayaayy, I hope dognose reads this. It is not Jens Sigsgaard but Johannes Siggaard 1890-1964. He assayed 1932-1960 in Copenhagen. It is an incorrect name in 925's
http://www.925-1000.com/dm_Assay.html" onclick="window.open(this.href);return false;. It should be corrected immediately. For your information Jens Sigsgaard was a writer not a goldsmith. The object, whatever it is, is made in Copenhagen in 1937. I would strongly suggest that showing the whole object would be much more appreciated than showing only the marks. It is also requested in the rules.
