Has anyone who has purchased one of the old-stock Bruyere St. Claudes from Smokingpipes experienced any finish problems? I got one of the Extra Billiards, and it's a great smoking flake pipe; great size for flake, good draw, etc. But it seems that when it gets a little warm, the finish seems to get tacky. No bubbling or blisters. I am wondering if they were found as raw stummels and only recently finished, resulting in an inadequate cure time. Any thoughts?
