[Bonetools] bone details with screw thread

[Katherine M. Moore]

Dear Heidi: These are almost certainly bobbins for making lace on a  
pillow, and similar pieces are still in use all over the world (though  
many of them are heirlooms).  Dating them or their use based on  
manufacture would be problematic.

Good luck with this though,

Kate Moore
