Iver Johnson BB


Iver Johnson bottom bracket, made in U.S.A. probably in the late 1920's. Solid steel with nickel (I think) plating. Iver Johnson's Arms and Cycles Fitchburg Mass U.S.A. also manufactured, as the name implies, guns. Which were also solid steel with (I think) nickel plating. Evidently they were adept at making steel tubes.
Iver Johnson famously sponsored the great American bicycle champion Major Taylor, whose is a remarkable story.


The fixing nut is left-hand threaded as is the cone locknut, which also serves as the extractor. Of the hundreds of tools, mostly metric, which litter my desk and walls and drawers and floor, not one would fit that loxtracter nut. I had to fabricate a one-inch flat spanner, which I might have to wait another thirty years to use.
