Just goes to show that with proper caution and determined care, what a cleaned artifact can be restored to! Very well done indeed!

Thanks for the positive replies guys and a big thank you to all those that responsibly venture into the wilds of northern Europe to recover these items.
Here are a final few photos that show the remarkable preservation that was uncovered due to years of silt build up and low oxygen.

Very nicely done! I understand that you want to leave it as it was, but indeed whit no climate control at home it would have been rusted even further. What did you use to clean it up?
