I'm so extremely a tootle puffer that I hadn't noticed all this happening. So, I googled and found a list!Essentially, except "chuff cap" is kind of outmoded. Once that style of cap started to take off, the format solidified somewhat and (likely due to simple popularity), rested on the Goon's design (810).
The first mainstream chuff cap I can remember was the royal hunter, and I believe it was quite significantly wider than an 810, if memory serves.
