At first he thought he had found an answer in a loose assembly from engine seven. The shape appeared similar, and one stamped character matched the damaged part. But an illustrated parts catalog showed that the version from engine seven belonged to a different drive arrangement. Its dimensions and intended load path did not match what Thomas had documented, and using it would have been an invitation to repeat the mistake with Curtis.
Noah wrote REJECTED CANDIDATE across the comparison sheet. He felt a fleeting disappointment, then noticed that the exercise had clarified the feature he actually needed to locate. He returned to engine eleven, the incomplete industrial unit with the intact protected drive assembly. The identification number on the component was partly obscured by old paint, but the visible characters pointed toward the generator's equipment family.
He called Arthur Benton. "I have an industrial drive component from an older engine family," Noah said. "The casting number looks right, but I need to confirm the revision before I take it further. Could there be two versions with the same outside shape?"
"There usually are when you least want them," Arthur replied. He asked Noah to describe the numbers and refer to the service bulletin Arthur had sent the previous week. They compared dates, configurations, and the parts catalog, carefully separating what they could establish from what still required hands-on inspection. Arthur concluded that the component was a plausible match, but would not certify its condition through a telephone line.
"That's what I thought," Noah said.
"Good. Tell the farmer you found a candidate, not a solution. That may sound less impressive, but it's the truth."
Noah phoned Daniel after nearly an hour of research. He explained where the candidate had come from, what the visible markings suggested, and which measurements and surfaces still had to be checked. He did not mention the earlier refund unless Daniel asked; there was no need to make that failure into a dramatic speech, but he would not conceal it if it became relevant. Daniel listened and proposed bringing the removed part to the workshop the next morning with Thomas.
"I'll be there," Noah said. "But before anyone installs anything, I'd like your technician to inspect it with me."
"That was going to be my condition," Daniel replied. "I like that you thought of it first."
Noah spent the evening cleaning the workshop and preparing a clear bench. He moved the unrelated components back to their labeled shelves, set out the manufacturer literature he had found, and made a checklist of the measurements that mattered. Rachel came in after dinner and asked why he looked more nervous than he had before his first sale. He told her he was beginning to understand how much responsibility was attached to a customer saying yes.
"You can tell him no," she reminded him.
"I know."
"Even after he drives all the way out here. Even if you've spent two days looking."
Noah nodded, though he had to think about it before answering. "That's the part I'm trying to learn."
