White tip vs. Dark green tip thin tower Cape hatteras

With the dark green tip Cape Hatteras selling in the first "Bill's collection" auction. And now a white tip going up for auction it made me wonder do we have any information on roughly at what number the switch from white to dark green was made

#4 is white
we saw that #240 is dark green
I know that #207 is dark green

Can we get any colors and numbers from personal collection here to see about how many of each there are ?

The last known number for a white tip is #160 from my tracking that I've been doing (Collectors books, Rutherford's books, Collector's Forum input, etc. This info will be in the product list I'm working on.

Now that I see the white tipped Ch1, I see that it has grey felt and that the dark green tip has green felt. Maybe the color tip coincides with the change to Canada for the last bunch of Ch1

It sure does.
