The first step was to search for any physical evidence relating to the ca. 1764 interior architectural trim that survived.  After looking at the evidence, the Restoration Team discovered that ca. 1764 nailers survived embedded in the brick walls.  Because every piece of interior wooden trim needs to be secured by nails, these wooden nailers were commonly installed into 18th-century brickwork for the installation of a room's architectural finishes.  Since these nailers can often reveal a great deal about the types and locations of missing architectural woodwork, their discovery was an important find.
