Can anyone help me with some of these marks?
So far i'm only sure its by or retailed by Anton Michelsen (AM and crown mark).
The EM monogram is so close to that of Erik Magnussen, but not quite .
But the really confusing mark is..
GJLD
GJ Limited ? I can find no similar Jensen marks though I know Magnussen did work for Jensen and Gorham.
It also has the London import mark with a modern L .
Can anyone help? Thank you , David
