Bonney Logo Stamp Timeline
This view allows you to browse the Bonney logo stamps through time. The best information comes from those stamped with a date code but we do our best to estimate production dates where no date stamp exists. In the June 1909 edition of the Automobile Trade Directory, Bonney is listed under the catagory "Wrenches - Nut & Bolt." They are not listed under that catagory in the January, 1908 Edition, nor are they listed in the October, 1908 Edition. Based on this evidence, we are estimating that Bonney began producing Wrenches (hand / nut and bolt wrenches, not pipe wrenches) in 1909, closely corresponding to their move to the Allentown, PA location.
