I recently found this unconfirmed Waddell scratch that I was almost certain should exist based on the Waddell (port) same sheet position relationship with Schulte (front view). There were four different Schulte scratches and two Waddell (port) scratches. Both Waddell scratches were exact matches with two of the Schulte scratches indicating they were in the same sheet position on two different sheets, therefore I was pretty sure the two other Schulte scratches would eventually be found on a Waddell (port) PD 150.

It really makes the research worthwhile when you find these
scratches that you think should exist based on a pattern.
