The completist collector in me is always grateful when ephemeral, disposable, parts like these tubes are still present; with pipes, it can be these tubes; with toys, the accessories that came with an action figure that were easily lost; with books, maybe a wraparound band that was folded over a dust jacket that announced a new price or award the book garnered—stuff that doesn’t always survive the ravages of time.
When I found my first 1st generation Savinelli Punto Oro circa 1958 with its inner tube still present I was incredibly happy. The second one was missing its tube and I will probably have to fashion a replacement—unfortunately, the whole pipe won’t be 100% original, but it will at least approximate something closer to its original issue state. As an archivist of sorts, it pains me when I see people discard these kinds of things.
