These guys can give you nine good innings.

They ALL were throwin' smoke!

The prior comment had be a bit confused, because I thought I knew enough about pipes/tubes to know what sort of varieties they came in - so I sought out the wisdom of the internet and discovered that "kalamein" is a process of putting a thin layer of metal over a base, be it for the purposed of fireproofing a wooden door, or adding corrosion resistance to iron pipe. It was trademarked originally as "Silvertin" pipe, unlike galvanized piping which is a thin wash of another metal bonded with electricity, kalameined pipes have a layer of applied sheet metal encasing the pipe.

Yes, probably more than we both wanted to know.

Wow. Most of these guys look like they could be murderers. Some more than others, but there are some serious stares coming through the computer screen.
