Damn. I'm most likely wrong then. Maybe I was thinking of some other tips.Maybe it's a matter of exact time period, but you may want to check the history of the Champion tip. The good ones, for example, made in the 60s and 70s, were calf skin, not water buffalo. At least this is what their recognizable red label box says. Here's one of mine, from the mid 70s. Although I have a few tips on the box in the picture, the words say "Selected calf Skin Leather, Turned By Skilled Hands," then in smaller print, Product of France, and Beware of Imitation. You can see part of the wording, including the word calf. I can take another picture if there's doubt.
Again, might be a different time period you're talking about. There were Champions and Crowns in clear plastic boxes afterwards, and there were Chandivert branded tips after that, which I'm not sure about.
All the best,

I need a correction.
