No asbestos, it was the old horsehair plaster, but most of it is gone now. Except for the second floor, we had to demo all the walls to do electrical, insulation, truing & leveling, and plumbing work, so it is mostly drywall, now.
The house is not a kit house (Sears, Aladdin, or otherwise). It was built by a contractor, the build permit being issued on April 25, 1917.
Did you do a plaster skim coat over the wallboard?
