Rauville- I can see the base screw now and the difference is quite apparent, is this a definitive sign that it's been made in more recent years? Yes, the starfish base and to a degree the top look more defined and even a different colour patina, almost like it's a different age or cast. I have no idea why these differences are apparent or how significant they are, hence why I'm sharing them with you guys for information.
I welcome skepticism, it was that which led me here in the first place! I appreciate you taking a look for me!
