One of the early competitors in the growing Tap & Die Industry was Winter Brothers located in Mansfield, Massachusetts.
A comprehensive history of Winter Brothers has been compiled by the family and can be found HERE.
The skills they used to start their own business were learned at S.W. Card (in Mansfield). The following is from the Winter Brothers Family Website:
"John and Murray took advanced math through the International Correspondence School of Pittsburgh. Allan would not go to high school, so went to work with his older brothers. They earned five cents an hour. Based on the knowledge and skills learned at the S. W. Card Company, a tap and die manufacturing firm, in Mansfield, Murray and John started Winter Brothers Tap and Die Company in 1900. (Simon W. Card came to Mansfield in the employ of John Birkenhead, who himself had come from Providence in 1868 to make spindles and lathes. With the invention in 1871 of machines to cut internal and external screw threads, Card set out to manufacture taps and dies, forming by 1894 the S. W. Card Manufacturing Co. The Card company served as a school for numerous die makers. John and Murray Winter, owners and operators of the Winter Brothers tap and die works in Wrentham, received their training there, as did several of those who in 1903 established the Bay State Tap and Die Co. in Mansfield. In 1913, S. W. Card merged with the Union Twist Drill Co. of Athol, but by that date, tap and die production was already a major Mansfield industry.)"
