[servicepub (RIP)]

One of my references (official SWW publication) states; This is a Wireless House Type body constructed of aluminum sheets on a steel frame. The inside is lined with 1/4" plywood, and the floor covered with 1/8" of Dektread. There are two sliding windows on each side and one in the rear door, all equipped with screens and blackout curtains. Sliding steps are provided at the rear door. The roof is fitted with aerial supports, and access to same is provided by a tubular steel ladder at rear of body on left hand side. A communication hatch is installed between body and cab. Ventilation is supplied through three ventilators in the roof, two of the static type and one power driven. A generator compartment is provided in the right rear corner to accommodate two chore horse generating sets. Ventilation for this generator compartment is supplied by two sliding doors, one at right rear corner, and the other at rear of body, right hand side. An operator's table is fitted at the front of body, as well as stowage space for storage batteries. Miscellaneous other items of equipment are also provided, including two bucket type seats, writing desk, luggage carrier, etc. A penthouse is supplied with this body. This body replaces the 3J1. A tool box is installed on each side of the body, at the front. A Jerrican carrier is mounted on each side of the body, at the rear. A one gallon oil can carrier, is mounted on the left rear corner, forward of the Jerrican carrier. Provision is made in the outside left wall for a spare tire carrier. This body is designed for mounting on a 4x4-101".
Another reference states "two folding seats". As neither uses the term DND seats I don't think that CMP seats were used.
