I know the BL had various versions of the L500, with ceramic and alnico, with different wires and different rails. The thickness and material of the rails seem to be an important factor.
My Custom Shop versions appear to be the same as the new "Rail" series in terms of construction (except for DCR, magnet type, and the sweet touch of MJ's magic hands!).
Pretty sure all of these different "Rail" versions are utilizing the same bobbins and rails they developed for the Jupiter series.
