This is the 3rd brake light trim from the trunk of a 1946-8 Plymouth (yes, Chrysler tried it way back then).  The red glass lens has been replaced by a blue acrylic sheet and an electric (corded) clock.  It is mounted to a carved piece of hardwood with four, short, round legs.  It is not illuminated.  The chrome finish is original & shiny but speckled with corrosion spots.

 

Shipping charged will be actual cost - no fee for packaging.
