I tried searching this topic, but found nothing specific enough. I just bought a nice, used Ludwig Black beauty, Monroe badge, serial number 3369353. I was told it was made in the late 2000's. It does NOT have rubber gaskets under the imperial lugs. There is a "BR" stamp behind the throw. The Ludwig site and others say that the shell is seamless, spun brass. I have heard and read that Ludwig black beauty shells are no longer spun, but are indeed seamless. I've heard that the "BR" stamp represents brass and not bronze. Bronze was supposedly a "BZ". I have also heard that the shells have gotten a touch smaller in the last few years, hence the use of gaskets to fill in the gap between the lugs and the center bead. Lastly, I've heard that the 70's models had a thicker and heavier shell, lending themselves to a "better" sound. So my questions are:
1. Is the shell spun?
2. Is the shell brass?
3. Is my shell the same size (shell thickness and diameter) as its 70's counterpart?
Any clarification on this matter would be greatly appreciated. I'm getting so many conflicting stories, I don't know what to believe to be true.
