Are you sure it is from Wanlockhead? I have never seen anything like that from there.
Is this the same specimen?

Hi James,
The barite was in Rock Currier's collection. Yes, it sure looks like the same specimen, just a slightly different angle. I was unaware that Rock uploaded it to Mindat. As for the location, I can only go by what was on the label.

Michael
You could ask on 'Where is it from' and see what is said. Hilton Mine might be a possibility
