This mark was found on a female ice skater and is in a style that can easily compete with pieces created by Schaubach-Kunst Lichte-Wallendorf in Thuringia. Which makes it even harder to understand how such a marking (or rather, the company behind it) remains unidentified. As the item in question bears the "US ZONE" addition, it was made between 1946 and 1949.
