Great news update!!! The Army National Guard Museum Curator found out where and when the vehicle spent its first 21 years, and better yet, have a Guardsman who spent many a trip in the Burb.
The person confirmed chrome bumpers, chrome hubcaps. It made it stand out with the other Military vehicles. The Government disposed of it in 1973. Looking for photographs of the burb and some of the Men who wrenched or rode in her!
