I've just finished working on a Burnham B48 lever filler from about 1950. A nice attractive pen in a black veined marble with some of the 'polygons' silver grey and the others are ?? Well they do look like a honey brown to me but they are, I think, described as Burgundy. The first thought is that it was burgundy and has faded, but the silver and black haven't faded and the picture in Andreas Lambrou's 'Fountain pens of the world' is the same colour as this pen and is described as 'Burgundy, grey black veined mosaic.' Faded or not, burgundy or brown, it's a good combination that works very well.
