The ornamental design for a shaft for a marking instrument, as shown and described. |
| Description: |
FIG. 1 is a top plan view of a shaft for a marking instrument showing my new design;
FIG. 2 is an enlarged scale left end elevational view;
FIG. 3 is an enlarged scale cross-sectional view thereof taken along line 3--3 of FIG. 1; and
