Existing comment: Johansson Gage Blocks, 1923
This was Henry Ford's personal set of Johansson Gage Blocks. Precision was so important to mass production that in 1923 Henry Ford bought an entire Swedish company famous for precision measuring instruments -- the Johansson gage company -- and moved its founder and headquarters to Dearborn, Michigan.
