Yes they did! It was a double wall alloy. The performance was right up there with the best & the durability was very solid. I got to test the prototype. For a point of reference, I'd put it's performance on equal footing with a '97 DeMarini UD with none of the durability issues. I was told that the production model would be even better as the prototype's walls were actually too thick. Unfortunately, its production coincided with the advent of composite bats (Ultra, Synergy, Genesis, etc....) Their appearance along with a hiccup in production made the bat financially unfeasible. Only a few were produced before the project was scrubbed. The subsequent abolishment of the 47/525 bat made any thoughts of reintroduction a moot point.
Will Vinci ever introduce a composite bat? Not impossible but highly unlikely!
I believe that I am now the owner of the bat that Smarkley3 had in his possession unless he had another.
