[Andre Murti]

Friends help to understand. These two variants of times of war. And who the possible manufacturer. Many thanks.

the pin back looks like a standard KO marked issued piece. I do not know enough about the clamshell screwback to give a good answer. MY guess is that these are 1920s and 30s pieces but that is just a guess.
MAYBE someone with a little more expierence will help out with the clamshell.

Is the clam-shell one-piece or the standard 3-piece construction (2 frames and separate centre core)?

Andre,
The pin back is indeed a KO which is an issue Iron Cross made during the war. The markings are below the pin and are hard to see in the picture, but they are there. The second one with the clamshell screwback is made during the 20's-30's and looks like one that was attributed to Deumer in another thread. I hope this helps,

The standard 3-piece construction not magnetic separete centre core.

This means the core is not made of iron which does not mean anything is wrong. Some cores are alloy such as brass or zinc. Apparently this was done becase the metal is easier to work with.

Thanks for the answer. In any case it is already possible to consider a post-war variant repeated manufacturing. Instead of original the period of war.
