Colt's Patent Firearms Manufacturing Company officially became Colt Manufacturing Company in 1964. This change reflected a rebranding and modernization of the company, which had been known for its firearms since its founding by Samuel Colt in 1836. The new name signified a shift towards broader manufacturing and marketing strategies in the firearms industry.
This is for COLT FIREARMS, not automobiles.
Colt's Manufacturing is a private, self-owned company.
