Master started out with very clear-cut styles.
After a few years, their styles blurred. I'd probably put them all in the "Sunburst" category ... while the purist part of me recognizes that they're very different from the Sunburst marble which was introduced in 1930.
Oh ... I just reread your post. I guess you might want to put them in with Comets since they present as opaque. But I still feel awkward about that. The lower left one might be a flat-out Comet. But would the others have come in a Comet box? I don't know.
After the early set of names (Sunburst, Comet, Meteor, Cloudy, Clearie), other styles came out ... and what did Master call them in their official company paperwork? For example, what did Master call their brushed patches? I don't know.
