"White of them," grunted Horman. "I suppose the same thing applies?"
"We're running over thin ice," said Kingman reflectively. "I can't afford to play rough. We'll make up their blocks."
"I wonder what they want 'em for."
"Something tricky, I'll bet."
"But what could you use two dozen gauge blocks for? All the same size."
"Inspection standards?" asked Kingman.
"Not unless they're just being difficult. You don't put primary gauges on any production line. You make secondary gauges for production line use and keep a couple of primaries in the check room to try the secondaries on. In fact, you usually have a whole set of gauge blocks to build up to any desired dimension so that you don't have to stock a half-million of different sizes."
"It's possible that they may be doing something extremely delicate?"
"Possible," said Horman slowly. "But not too probable. On the other hand, I may be one hundred percent wrong. I don't know all the different stuff a man can make, by far. My own experience indicates that nothing like that would be needed. But that's just one man's experience."
