I might be a little late to this party but I have three APSC pipes from 1980. Super early pipes. I had a new stem put on one of them. I sent it to Mr. Tinsky and from what I understand, he had some leftover stem stock from the earlier pipes and an old decal (star with no circle) that he put on the pipe for me. The middle one has the new stem. Really great pipes with an amazing back story.
