Harris Ranch Barbed Wire

Three varieties of barb wire observed at Harris Ranch as identified via the Barbed Wire Identification Encyclopedia. by Harold L Hagemeier, (Fifth Edition).

Gliddens Round Single Strand - Patent #RE 6913

Curtis Half Twist Half Round Barb - Patent #470,747. Less confident as it is hard to tell if the barbs have been twisted 1/2 turn, or rather I am not sure of what that would look like.

Not too sure on this one as only have the single barb to go by,  but proably a Curtis variation.
