Revolution uses cores and covers from (and is probably produced by) Brunswick, and the brand is still active in Asia - you find a lot of their stuff in the Japanese and Korean market.
Most of the time they use retro-material on the covers, but also some state-of-the-art cores. There had, for example, been a ball series 2 years ago that used the low-RG Inferno core and PK18 covers (Rev-Checker, if I remember correctly). Generally good ball's I'd say, and the brand has been around for 10 years I think.
Their website revolutionbowling.com has been down since about 2 years, but the balls still pop up in Asian online pro shops. Just remember that most of them are mid-range Brunswick balls, nothing fancy.
