The Campbell Surrey seats 11 in relative comfort. The body is framed and floored in ash, with 1/2-inch marine-type mahogany veneer plywood panels. The roof is made up of basswood strips, covered on top by insulation, a layer of cheesecloth followed by a rubberized cotton sheet that's tacked to the top with strips. Much of the original wood was intact for the restoration, but the floor and roof both needed extensive repair and replacement, and one mahogany side panel was replaced. This was a testament to Campbell's preparation almost 60 years ago. After being treated with filler, the wood was rubbed down with oil and given two coats of a tough exterior varnish and dried in a booth at 80 degrees. When dry, it was hand-sanded and given another final coat of varnish.
