Thanks for posting some more pics, still leaves me puzzled though!
I note on the reverse core there appears to be areas of rust? If the core is zinc, surely this wouldn't happen? Could it be the core is in two parts, zinc on the front and iron on the back?
Looking for LDO marked EK2s and items relating to U-406.....
yes it looks it has some rust on it, I don't know I have rust on my zinc small frame Juncker too.
I don't like the signs on frames but I 'm not convinced yet that it 's fake.. bah..
