I was thinking of getting an original floyd rose off ebay, and I saw one new and from a refutable seller advertised at a good price. I looked at the pics and the tremolo arm blocked the area where the stamp usually is where it says "Made in Germany by Schaller" so I messaged the seller, and he replied back saying that (supposedly) there are stamps on the back that say "Made in Germany" although not by Schaller. I heard that any Floyds made in Germany are original, but I thought the real ones were all made by Schaller...Is there anything to worry about in terms of authenticity if I want to buy it?
