Just a side note of curious trivia if your interested. Back in the 80's and early 90's I ran computer field service, and one of my customers was Armstrong World Industries. Those of you who know flooring and ceiling tile recognize Armstrong as one of the leaders in those products. They had several plants in Lancaster county as well as all over the world. At that time, at their R&D facility on Columbia Avenue in Lancaster, they had a little building out back with an engine dyno in it. I serviced the dyno computer a number of times over the years, and learned that Armstrong made a lot of head gaskets for Cummins, Felpro and other companies. Cummins would send them whole engines to test their gaskets in, and they pushed those motors hard. Armstrong made that stuff, because they were experts in working with fibrous laminated materials. Today all that stuff, and several of the plants are gone. Ms. Smith's Pies used to make aluminum magnetic shields for RCA, that got put in television picture tubes, because Ms. Smiths was an expert at forming aluminum.... for pie plates. We give a lot of credence to the companies who's names go on products, but often don't get to know the truth behind where they come from. We would feel differently if we felt we were driving around with a piece of linoleum sealing up our blocks, but the reality is not far from the truth. This doesn't make a hill of beans difference, but the companies who supply the raw materials for a lot of things come into play also. We have our favorite brands, but must remember that there is a lot of sometimes seemingly unrelated science behind a lot of what we use and purchase. We like those brands perhaps, because they look out for our best interests and try to bring us the best product for the money, and the only difference may be the quality control or the packaging, or the customer service.
