Thin Interior Walls-what to do?

[Lance Balkus]

Anyone had any experience with the thin interior wall homes? This wall has no studs but strips of vertical drywall sandwiched between a set of 1 1/4 drywall sheets. The home has multiple original walls built this way in the early 50's. This wall runs perpendicular to the ceiling joists, so it would typically be a load bearing wall. These walls obviously have no wiring in them, the house needs to be rehabbed not sure if I should remove and rewall them.
