Lot of sixteen old clear glass insulators for telegraph or telephone lines, dating to the 1890s and the early 1900s. These are several makes and sizes, about 3 3/4" to 4 1/4" tall.
These are all very heavy, and would make bookends, door stops, paperweights etc.. They make good string or wire holders, too (like giant spools!)
Many of these have some chips (large and small), all have wear, scratching, soil etc. from use.
