Yeah I was wondering about the colour, as far as I know they were available in black and turdburst, never seen a white one. Serial number and the Broad Bass decal puts it towards the end of the run I think, so 80 - 81 ? Could be wrong about that.
BB1000 and BB1200 would also have had that bridge. Tuners look right - what I can see of them is identical to my BB800. Hard to tell but it looks like the nut might have been replaced with a thinner one and a shim.
