I think the meerschaum linings appeared in the 1950's and 60's when pipe smoking was still a mass market and gimmicks, if you will, were pumping sales and marketing. In that heyday, the meerschaum linings were often combined with stitched leather coverings of stummels, for a fancy upscale look. Stingers, the metal condensers inside the stem, were similar sales gimmicks, though they appeared somewhat earlier. Folks have gotten good mileage out of the meer lined pipes, but I don't think they are much of a sales pitch today compared to the old days. As an earlier post said, I think one might want to opt for a full meerschaum pipe rather than a liner, if you have a choice. However, if the lining appeals to you, or the stitched leather bowl, go for it. Not bad ideas, just not the glamour look they once boasted. It really takes a commuter train platform and a smoking car to be fully appreciated by the smoker and his audience.
