............Book say Black enamel. Interviews with the guy on the line said black lacquer.
"Book" ?? Dave what book are you referring to - the assembly manual?
You referred to my pictures posted earlier and I think its going to be difficult to tell the type of paint from those. We "know" that the pinstrip was applied at a different time and I think it was applied with the roller style hand held machine that was so popular at the time. Lacquer is the most logical paint giving drying time and other benefits
