800+ Year Old Buckle Cleaned Up

[Full Metal Digger]

Hi Friends,
Some of you wanted to see this tiny iron buckle again once I got it cleaned up. I soaked it for 6 days in CLR and that got 99% of the rust off but the tongue was still fused into the wrong position. I soaked it for 3 hours in WD-40 and that did the trick. Over 800 years old and the buckle still works!
