I don't think I ever used it here, but my screen name on Reborn Pipes is still "Upshallfan".
I grew tired, over time, with the maintenance needed on the molded stems - they turn green literally overnight. And compared to Ashton (Taylor), Sasieni and Comoys, I became "stem picky" and preferred them So, nearly all of my Upshalls were sold - save my Silver-Spigot B, which has a new Cumberland stem to replace the original.
Ken Barnes said here somewhere that he regretted not investing in handcut stems for James Upshall, at the time, it was a cost savings decision.
