This is a nice porcelain Olympia 1936 Saving Bell (“Spardose Olympia Glocke”).
It is in very good undamaged condition and also the lock is in full functional condition.
On the bottom it is marked with: “Erzeugnis der Porzellanstadt Gelb, Bayer Ostmark”.
Extremely rare and of an absolute rarity is that the original key is still present! In all my collecting life this is only he second Olympia 1936 saving bell i have ever found which has the key included. These keys were originally only kept at the bank and were not in possession of the people. Finding one with key and being able to open and close the bell, is very very rare and the key is with certainty much rarer than the saving bell itself!!!
A rare chance to get a bell in perfect condition with key!
