Found this in the UK. Looked like it had come off the Titanic or been sat on a beach for 30 years. Could only get the nickle to shine so much (2nd pic), so it was off for a re-plating.
Excellent job. Stunning. I don't know if these were actually exported. Perhaps it was spirited out of the country. When it's my turn as Prime Minister this one will be on my list for recall. Cheers.
