A dye named durazol blue has been suggested as a replacement for methyl blue in Lendrum’s MSB. It is most likely to be this dye, durazol blue 4R. There is another dye named durazol blue 8G, but it is a copper phthalocyanine and is unlikely to be the dye meant. Unfortunately, the dye was not specifically identified and it is not clear what dye is meant.
