Exercise much caution when purchasing these decorated German wood ratchets. The plain ratchets themselves were made in huge quantities, and many remain extant. What some dealers do is marry a plain, vintage wood ratchet with a vintage, but otherwise not connected, Halloween decoration and sell the resulting union as an original. Now, I don't believe that was done for the item shown here that sold for $189, but this marrying frenzy is something to keep in mind when you are shopping for items in this genre.
