Late to the party by years, but:
I had a bike from Bella made in 1981. Ed Blank had his little shop up near Lechmere Square, in an old brick mill building. My riding buddy Mike Battersby was his assistant builder. Mike just passed away late last year, after living in Brazil for many years.
My bike was indeed made from Super Vitus with brass and Cinelli crown and BB. They were such nice bikes. Ed paid a student at Mass College of Art to do the decal scheme. As with so many frame builders, Bella's business dried out when the mountain bike craze descended.
I think Ed keep bike racing into the masters categories. I had heard when Bella closed he worked in his family's business.
