The ornamental design for a portion of a jighead, as shown and described.
FIG. 1 is a front side elevation view of a portion of a jig head according to my new design, which is shown attached to a fishing hook. The rear side elevation view is a mirror image of FIG. 1.
FIG. 2 is a top plan view of the jig head portion of FIG. 1. The bottom plan view of the jig head portion is a mirror image of the jig head portion shown in FIG. 2.
FIG. 3 is a section view in elevation along the line 3—3 in FIG. 1 showing the left side of the jig head portion of FIG. 1; and,
FIG. 4 is a right side elevational view of the jig head of FIG. 1.
The broken lines, including those showing the fishing hook, are for illustrative purposes only and form no part of the claimed design.
