This is BM Super - endorsed official model by Dr. Brian May.  This particular guitar has been upgraded beautifully by Kz Guitar around its bridge because the Wilkinson bridge was not always perfect. 

The development story of BM Super started in May 2007 when BMG, Mr. Greg Fryer, Kazutaka-san (Kz Guitar) and I gathered in Sydney to discuss framework parameters for this guitar.  At the beginning we called it BM Elite which later turned out to be difficult to use.  It took incredible amount of efforts, costs and patience to launch and continue manufacturing, which Kazutaka-san had to bear.  It was the initial agreement to make 100 units per year, but in fact more than three years were necessary to reach 100.
