From the inventory of a store that closed around the turn of the century, it was held in storage before being purchased by us. It appears to have been opened, which was not uncommon in those days. Item was not tagged as being defective but is untested by us. Due to the limited testing and, because vintage components can fail at any time, it is sold as-is, officially "for parts or not working" with no guarantee of functionality or completeness whatsoever.
