Rebecca asked Noah what he wanted from the cooperative. He considered offering repair services immediately, then remembered the scope of the work he had actually performed. He said he could help identify older components, research availability, and supply parts from his inventory when their identity and condition could be established. For repairs or installations requiring specialized qualifications, he would work with experienced technicians rather than claim authority he did not yet possess.
"You want to become a parts researcher?" Rebecca asked.
"Maybe at first," he said. "If I keep learning, I might be more later."
She smiled faintly. "That's a more interesting answer than most adults give me."
The cooperative did not hand him a large contract that afternoon. Rebecca offered a trial arrangement with clear limits: she would send a small number of difficult identification requests, Noah would provide written findings and availability information, and the cooperative would decide whether to purchase anything after its maintenance team reviewed the documentation. Rachel would help handle the business paperwork while Noah was under eighteen, and nothing would interfere with his school attendance. Rebecca made it clear that reliability over time mattered more than one impressive result at the Mercer farm.
Noah accepted the arrangement with relief. An immediate, sweeping contract would have frightened him if he had been honest enough to admit it. He knew the difference between cataloging parts on a quiet Saturday and responding to several urgent inquiries at once. The trial gave him something specific to prove without asking customers to risk their operations on his enthusiasm.
The first request arrived the following week. A grain elevator had an older industrial drive with a damaged housing cover, and the maintenance supervisor wanted to know whether Noah had the correct version in stock. The description sounded like something from engine thirteen, and Noah spent an evening checking the stamped numbers and measurement references. He found a promising similarity, then discovered a production revision that changed how the part sealed against the housing.
The component he possessed was not the correct version. Noah reported that conclusion to Rebecca with photographs and the conflicting part numbers attached. He expected disappointment when she telephoned the next morning. Instead she thanked him and said the maintenance team had nearly ordered a different used part carrying the same misleading description.
"You just saved us a bad purchase," she said.
"But I didn't find what you needed."
"There's more than one way to be useful, Noah. Finding out what not to buy matters."
The second request involved a pump accessory assembly from an engine family similar to number sixteen. Noah checked the documentation, measured the candidate, and arranged for Arthur to inspect photographs of a wear surface before he represented it as usable. The cooperative's own technician performed a final inspection after delivery and accepted the component for a planned repair. It was a small sale, but it included exactly the sort of records Rebecca had asked for, and she paid the invoice without dispute.
The third request remained open for nearly two weeks. An older generator at a remote equipment shed carried a nonstandard modification from a previous owner, and none of the published drawings matched the installed configuration cleanly. Noah searched through Earl's notes and several manuals but could not verify a compatible part. Rather than select the closest candidate and hope, he wrote an explanation of the uncertainty and recommended that the cooperative obtain a specialist assessment.
