Trying my best to get a few example pages up, which will eventually need to be extensively edited and refined. Whenever possible I am using material from pipe maker websites, about themselves, or at least endorsed by them by virtue of appearing or their websites or linked to from them. Some of this material is copy written and permission will eventually be sought by the authors, or if not given, those materials will be replaced with original material.
At this time we can make no specific claims as to the accuracy of the material presented, other than we suspect it is accurate. Some of it is perhaps a bit dated.
