Although this candy container is uncommon, I have seen a number of them and all have a spring tail. I suspect the chenille tail is something added to it sometime after its purchase from a store.
The seller of this pleasing candy container contacted me, saying that photos of another such container show a red chenille tail. She asked if it was possible the container was made both with chenille and spring tails. Here was my reply: "Thank you so much for your email. (By the way, I very much enjoy the quality of your listings!) It is absolutely possible that the Germans made two versions, one with a chenille tail and one with a spring tail. Existing documentation on when such things were made and what original materials were used is quite incomplete. Production of goods back then was idiosyncratic, something not really true today. My guess is that if the Germans actually used chenille when completing this whimsical candy container, they used it when the supply of metal springs for such decorative purposes was low to non-existent. (This would have been the case ~1935.) A plausible unifying theory is that the earlier candy containers had spring tails and a few produced very late in the run may have been made with chenille. A discordant note about the use of chenille is the color. I would have guessed black or orange would have been used, not green and red. In the end, we’ll never really know why such decisions were made. Thanks again for your email!"
