Maintenance Man

Maintenance Man is an unmarked quest $$

After a brief conversation with Calvin Whitaker, he will buy any tools from the Sole Survivor for 15 caps a piece. The tools he seeks include:
 * Adjustable wrenches

 * Hammers
 * Screwdrivers

Calvin will not buy any other tools from the Sole Survivor, even ones that would seem to make sense, like gardening tools and cleaning tools and some uncommon hammers.
