Found these small german ones in the attic of a church in Stuttgart, the church now is in the process of renovation, so these guys went straight into my collection. They have about the size of a big fist, so they are really small. Maybe this position here is not the original one, because their last use was to hold the cable and string of the lights down in the church. In the beginning of the 20th century, the attic of this church was used as a storage for hop and malting barley by a local brewery.
