So far, I’ve assumed that they ended with these plastics, with the logo on the front. Before that, they were using green boxes, some time after the Altos were added; the logo was on the back on those. Before that, there was no colour-coding, with the Soprano having a red box. Going back even further, there was not even a “Soprano” on the box.

The Soprano that doesn’t show a well-shaped mouth-piece really doesn’t have a mouth-piece at all.
