rare barbed wire

1. Miller Six Point (1043 B). To me this looks like a coiled up bug on a single strand. A very symmetric wrap that has 3 barbs per 18". A variation of patent #181,533 by Charles W. Miller of Sycamore, Ill in August 1876.
2. Kennedy Five point (206 B). I have my doubts about this wire. These barbs were supposed to be purchased by the bucket and hand applied. This example is way too thick and heavy for that kind of application. I'm not sure what the history is on this wire. If anyone has more information I would greatly appreciate a comment. If indeed a Kennedy, the patent number is #153,965 filed by Charles Kennedy of Hinckley, Ill in Aug. 1874. There are 2 and sometimes 3 barbs per 18".
3. Munson Double "Z" Double loop (158 B). At the Pueblo show I saw 5 examples that were all different with respect to wire thickness, barb length, loop size. etc. An amazingly variable wire. Patent # 214,417 by Andrew M. Musson of Lee, Ill in April 1879. Two to three barbs per 18".
4. Childs Twisted Double Ribbon (1152 B). A unique design of 2 sheet metal strips with a 2 point sheet metal barb between. Patent #285,229 by J. Wallace Childs of Chicago, Ill in Sept. 1883. There are 3 barbs per 18".
