Cast copy. That is obvious on uneven reverse side and eagle head coupled with wings.
I'm sorry, but that is a very bad copy. The whole character is very unclean.
The pitting on the reverse is a giveaway to this being a cast fake as stated above.
Looking for LDO marked EK2s and items relating to U-406.....
More specifically, it's a crude casting of a Souval Minesweeper with a spurious "4" mark added for good measure. It's interesting to note that this faker went on to improve the quality of his reproductions. Here you see two more examples of this fake Souval showing progressively increasing sophistication.
Very bad copy. They are showing up more and more these days.
Thank you for your comments. I guess you win some and lose some.
