Thread for random remarks and questions about Voynich images

Sorry I only have my phone right now. Not really a rivet, but the bottom half of the oval appears disconnected from the top part. On the right side of the oval there appears to be a circle which could be seen as a joint between both parts. But again I'm not sure at all. I just have a hard time seeing the bottom part of the oval completely connected to the rest of the object, if that makes sense.

(it's really difficult to explain these things without my trusty Photoshop)
