This was on ebay and an offer was excepted. To me it looks very much like a very enthusiastic copy. The blue is so very blue the brass studs are sooo old looking. Glad I paid at least 10 times less. I have saved pictures for when the ebay ones have gone. Also flint rather than rhyolite which is clearly discernable. One easy to nap the other hard.
