Hank Sterling and Arv Hanson have a lot in common. Both work at Swift Enterprises. Both work on most of Tom Swift’s major projects. Both have a lot of respect for their young boss.
But, there is single, a small issue that has plagued both of them for years: practically nobody at Enterprises—specifically people who have not worked directly with them (and even some of those)—truly understands that they do two very different things.
Hank makes patterns for all of the individual pieces that go into Swift planes, trains and—if they made them—automobiles. Arv makes all of the intricate models that sit on the shelves in Tom and Damon Swift’s offices and laboratories.
Finally, during an important military project they hit on a way to help people tell them apart.
This is the story of that project and how they finally got people straight on who’s who!
