As the links above are now obsolete I will attempt to display as many Danish silver plate marks as I can.
There is a great website with the history of Cohr silver and the marks used by them which are very useful.
This information is given in a history of Cohr silver at http://www.cemifor.dk/cohr/index.htm
The first photo below shows the torch mark that was registered in 1929 by the "Common Representation of Danish Goldsmiths" (FDG) as a trademark. They wanted it to be used as a quality mark for silverplate sold by the members only.
The torch mark is shown with letters FDG this was used from 1929 to around 1932. The letters DFA stand for Dansk ForsÃ¸lvningsanstalt KÃ¸benhavn as above. The name DANA which I think may be the trademark for the silver plate produced by the company the same as Cohr used ATlA as their silver plate trade mark. I have seen DANA on many cutlery patterns. I may be wrong but it seems logical. Last is P for plet meaning the piece is plated. http://i53.tinypic.com/2u8ueqp.jpg
The next shows the same era torchmark with larger letters and also shows Cohr Silver's trademark for silver plate ATLA in usef from 1926. It also has a DTA mark for The National Association for Danish Enterprise, an independant organisation created to support and market Danish produced consumer goods in Denmark and abroad. ( see Cohr history link above). The last mark is 30 indicating the thickness of silver.http://i52.tinypic.com/10o446u.jpg
The last mark in this group again shows the torchmark with small letters FDG has the name ABSA and the detailed figure of Absalon. As above I think the ABSA may be a silverplate trade mark for the Absalon Silver. There is a P for plet meaning plate.
