This is intriguing, and supports my hypothesis that we were actually a powerful _exporter_ of bronze-age metals (as every geologist over the age of six knows) and that we didn’t need to be an importer. The neo-importatistas, hysteircally-climbing onto the anti-English bandwaggon for re-writing history, since this is needful for them to survive and get “research-grants”, are clearly revisionist-Eurocentric “historians” who want to pre-justify the EU and all its works. Bugger them, for a start.
All they have to do is an isotope-analysis of the copper and tin ingots found on board, to know whether the metals came from here (probable – it was in the South-West, after all, the copper-tin-silver-gold-zinc-lead-cadmium-mercury region of the UK, and why would you bring foreign coals-to-Newcastle?) or were coming from somewhere else such as Spain, France or wherever.
