This week I have another guest Mystery Object for you from regular contributor Joe Vans:

This is a tricky one, and while I think I have a rough idea of the element and Family, I’m still not sure of the species this comes from, so all suggestions are very welcome!

As always, you can drop your ideas, questions and suggestions in the comments below, and Joe may be able to provide some additional information and I may offer some hints as to my thoughts if needed.

Have fun!
