are 16 vintage, ceramic knobs and tubes used for putting electricity into a house around the 1900's.
The tubes were fitted through the studs and beams , and the wiring was run through the insulating tubes.
1 is 2 1/2 inches long, 1 is 4 3/4 inches long, and 14 are 3 1/2 inches long.
Some are chipped, but overall they are in pretty good shape.
These could be used in restoring an old house, to add to a collection, or use your imagination in crafts!
Thanks for looking!
