Problem is that OGH is not registered as a Danish maker's mark. But Olaf Gunnar Hjertzell did register this mark in Stockholm Sweden in the 1930's.
Another possibility mentioned in a topic from 2005 was that it was in fact DGH for Danske Guldsmede Handvaerk.

The mark on this silver-mounted glass vase is, in my opinion, clearly OGH and not DGH. The vase does not have a Swedish import mark.


Does someone have an explanation why this vase is marked for Olaf Gunnar Hjertzell and also DENMARK?
