12V on/off rotary switch with wood panel trim. The back is a grain pattern printed onto a steel panel. The knob is a black plastic.
These are "new old stock" that were sitting in storage at a dealer for decades. They have dust, some shelf wear, and on the back they may have a little surface rust. They are in excellent working condition.
Orginally used in some Road Runner, Jet, Aristocrat and other vintage trailers.
