[1][2] The Regal Motor Car Company of Detroit, Michigan was established in 1908 as a partnership between brothers Charles R., J. E. and Bert Lambert and Fred W. Haines.

The car was widely publicized and a factory stock 30-hp Regal nicknamed "Plugger" crossed the country 5 times in 1909 and 1910 covering 22,000 miles.

The Seabrook Brothers who had a large automotive accessories business, branded the Regal as RMC and Seabrook-RMC for the British market.
