Armstrong-Blum Manufacturing Co. was founded in 1904. It became the
Marvel Manufacturing Co. of Oshkosh, WI. Marvel's website went down at the end of 2018, and now redirects to Amada Machinery America. Armstrong-Blum and Marvel were best known for their
Marvel Draw-Cut power hacksaws.
Spartan was a brand name that Armstrong-Blum used on products manufactured by a Taiwanese partner (not covered on this site).
