Mostly old ones. On the left, a 1930s "Radio," a burnished Tibbes No. 2 1/2, burnished 1960s Freehand w/ cob shank. Big long ones are by Phoenix-American Cob Pipe Works (left), unknown (right). Upper with fancy-turned bowl and only one bend in stem was made by Hirschl & Bendheim. Top right is a Tibbe's No. 1. Not shown: a Tibbe's No. 100 sans stem (a shortened No. 1 with a slightly different shank) and another No. 1, also missing stem, but having several extra shank sections; it uses the same sections (in this case, 'radiator,' straight, 'radiator,' and the fancy spindle-shaped end piece) as found on the super-extended ones on one of Missouri Meerschaum's 1904 museum displays, just less of them. Perhaps they made more like this, or maybe someone saw the displays at the Exposition and requested one?
I'm still hunting for more of the early lathe-turned Tibbe's pipes, and the corn cob cigar holders, which were made first with wooden mouthpieces (the glass case in Missouri Meerschaum's museum has several of this type), then later with a nickel-plated ferrule and a plastic mouthpiece.
