I am not sure who made your marble but it doesn't impress me as Ravenswood, even though it might be. Every WV swirl maker produced simple transparent swirls, and many used UV reactive glass. Many times, an ID simply cannot be determined with any confidence. This isn't usually an issue because the collectible or monetary value of the marble won't really be affected regardless of who made it.
On another note, the article you cited from the archives was not written by Alan Basinet (Marble Alan).
