REMOVAL OF FIRST TRUSS. The first truss removed here rests on ground plates and awaits the similar placement of all the trusses for temporary storage. In the foreground are cut out sections of roofing also removed by crane. Note the 1873-74 standing seam sheet metal roof above the 1851 shingling. The roof pole gutters were in part made up of bench back rails. - Twelfth Street Meeting House, 20 South Twelfth Street, Philadelphia, Philadelphia County, PA
