My grandmothers tapestry bobbins

I am wondering if any of you are familiar with these bobbins?
They belonged to my grandmother and she isn't in any shape to answer questions about them any more. I think they are beautiful, but I really don't have a use for them. I am hoping someone knows their origin and whether they are really used for tapestry weaving on high warp looms. They are quite large so I imagine they were used with large weft bundles.

I am also curious about these shuttles. Does anyone have working models of them? How do the bobbins fit into them to actually hold the yarn? They have metal tips and I imagine would take quite a beating. With the metal loops sticking up they must go through a huge shed! These also belonged to my grandmother.

Happy weaving!
