"Were made by the Crescent Tool company. The name stuck..."

But why did they call it the 'Crescent Tool' company? Obviously, there is much more to this.

I think the real question is "Why haul a wrench around in the first place?" Was he looking at trying to get into an access panel somewhere?

The meter (VOM?) raises a question, too. While it could be used to check his detonator circuit, you would think that had been done at the appartment or wherever he put the bomb together. So, maybe he was trying to check either an alarm circuit or something else.

Curiouser and curiouser....

The company's founder and the wrench's so-called inventor, Karl Peterson, really did nothing more than buy the design from a Swedish immigrant, who had seen similar wrenches made in his homeland.

Those damm Swede møøslimbs!
