Production — Blue wadding on top
The top of a war housing trailer comes in for attention at the Los Angeles plant of Western Trailer Company.
High catwalks give easy access to the top as blue wadding is laid over the entire surface. The spongy softness of this material will compress under the final fabric top. The wadding covers all nail and screw heads and any possible rough edges, ensuring a smooth final job.
