Thanks for the answer to my question. I have not yet ventured into this side of collecting. Knowing where and what they were used for makes it very interesting indeed.
The badge with the Kyffhauser monument above swastika is the central piece of a cap badge and wreath. Here's mine to compare.
You have a nice selection of tinnies already, somewhat overlooked by some collectors, but I love them, so many different types.
Great collection, keep going.
