Part 3/6:
Examining the specifications, the author references a label, though it's somewhat obscured by dirt. To gain clarity, he plans to enhance photographs of the label, reflecting a careful approach to documentation. The generator is identified as a Westinghouse type DC generator, potentially a model with specific design traits worth further investigation.
He considers whether the generator's construction involves cast iron or forging, intending to test with a file later—a traditional method to assess material hardness and infer manufacturing techniques. This detail points to the importance of understanding the material quality of historical machinery.
