The Chewbacca’s were found to have used the same hair as the 75 Kirks, about 10-11 years ago. They are from the years 75 to 78. There no certainty with other Don Posts masks. But the vintage Chewbacca’s come up on ebay about twice maybe 3 times a year. I immediately got 2 of them, 10 or so years ago, they were $50 then, and I rehaired 6 masks with real Kirk hair. I have a stored stash of the hair.
