Found this in an old thread on Cue reviews some decent info on these cues
From Member Cueman
Biagio is just a brand name that is owned by one of the major billiard supply companies. The early Biagios were made by Billiard Cues of England. Later by Joss and then other Asian companies. They just kept using that private label brand name and got them made by whoever they wished. The BCE and Joss made cues were were good quality. I have no idea of the quality of the Asian made ones now. Later ones would be harder to pin point who made them, but the early ones by BCE (Billiard Cues of England) had a nylon shaft insert and a 3/8-10 thread pin. That was the first cue I ever saw built with that joint combination and they were made in the late 1980's.
