Ok so, I haven't bought this one... yet. LOL! I was wondering though if anyone could give me some info. It's a Round Point 6/8 Marked "BISMARCK" on one side of the tang and "Ground in Germany" on the other. It has "F. Everard Southampton Agent" etched on the blade. What is this? Is it a good old vintage Bismarck? And, what's with the etching on the blade? The scales are plain black and the seller says it's English Silver Steel. Any info would be greatly appreciated...
