Archeaologists and Metal Detectorists have an uncomfortable history. For years after metal detectors (AKA mine dectectors) become available to the general public, the Archealogists declared war on these hobbyists. They were treasure hunters and would rob the valuable metal finds and destroy the historical context.
This guy appears to be the modern day detectorist. He immediately notified the authorities and is cooperating in a proper excavation. It’s hard to imagine that someone who owned this chariot (An iron age Lamborghini) also lived in an Iron Age round house, but that may be the case.
I Britain anyone finding a historic treasure is required by law to report the find to local authorities.
The find is then turned over to a local Archaeologist to excavate.
The finder is then given a monetary reward % as defined by law based on the appraised value of the find.
The finder does not get any of the actual treasure.
