My collection of all but one of the known types of wood warning block barbed wire.
The center wire is the only known specimen of the Merrick Mihills diamond shaped block with spur rowel known to exist.
The seventh wire from the top is a recent addition that was on my radar for 50 years before I acquired one.
The second from the bottom is a replica that I made. I used picket fence wire whose pickets had rotted away. Henry B. Schwartzengraber and Charles C. Bliss, of Delphos, Ohio were granted Design patent no. 19,482, December 10, 1889. It most likely never went into production as there are no known specimens in collections or museums.
The third from the bottom wire is possibly a fake. It is only the second pin block wire I've seen with a sheet metal barb between the blocks. See fourth photo. It would be fairly easy to spread the wires and insert the sheet metal barb. There is no mention of the variation in the patent for the design. However, the manufacturer also made wire with the sheet metal barbs, so it is possible that this is a transition, an experimental variation, or possibly a special order. It's fun to speculate.
