I have loaded up some pictures of what they did. The nails are along the rolled over sides, and on the underside where the metal is rolled under. on the Flat side, facing out it is smoot and clean, no evidence of ANY nails unless they were covered and filled.
Huckster: BedLooked at the photos... in pic 21, not sure what part this is-the blue looks like "primed wood and the white the metal, but it does look like nails/tacks are every 6-8 inches. These pics are of the finished panel as the photos just before look to me to be of the metal panel being clamped on to the wood frame, notice the tack hammer on the table. Tar was sometimes used as an adhesive for the sides of the panel.
