Antique wooden item, 1920s

We don't know what this small item is but you can tell it is a very old and unique item. The way the wood is put together, the joint, says a lot about its age. Maybe it was used as a children's toy, because it wobbles, maybe it was for a special use but maybe it should be the other way around. In any case, we thought it was a special item and we are sure there is someone who thinks so too. The dimensions are: 28 cm width - 17, 5 cm hight - 18, 5 cm depth.
