There was a series of pictures both here and the Bryce Forum gallery, about a year, year-and-a-half ago, of complicated, textured, etc. piping for some warehouse. I remember seeing them, but I'd go to the Watchful eye place first.
Once apon a time there was a place called Lannie's 3d, that had a pipe kit in the downloads section. The place is no more, but if you have the URL from then, you could go into the Wayback Machine and see if it got archived. Good luck

I wish I'd said that.. The Staircase Wit
