Mike,
We had talked about this a long time ago, but it has not been tampered with. The edges of the stampings are still raised up from being stamped. I'm on my phone typing so the thread search is not availible for me to look up original thread and see when it was. I do believe that it is or European lineage on the stampings. Like I said above I messed with it by refinishing it from being blued.
