Eric,
Is the Maine Two Foot Display that Mr. Mead built, and had at Allaire still there? As I recall, it contained No. 6's front number plate, an Eames Vacuum Brake Co. vacuum hose complete with gladhand and some nice (for the era) On2 models and it had a selection of B&SR and B&H switch locks and keys as well.
. It used to be on display in the Freneau, NJ (ex. CNJ) Depot building.
