In 1859, at the age of 23, John Marston's apprenticeship was completed and he bought Daniel Smith Lester's japanning business at Bilston which had amalgamated with Fred Walton & Company and Thurston and Company and established his own business
John Marston Limited, producing japanned tin goods. He did so well that when Perry died in 1871 Marston took over the business and merged it with his own. Between 1899 and 1901 they also experimented with prototype cars, but none were sold. Marston disliked motorcycles, as he saw them as dangerous and never rode one or drove a
Sunbeam Motor Car Company car, but remained a keen cyclist, most often using a tricycle. Many John Marston Sunbeam motorcycle models were produced and the first was a 350 cc in 1912 followed by a range of 500 cc singles and some v-twins. In 1924 a new model numbering system was introduced; Sunbeam Models 1 through 11. Other higher numbered models were produced in later years. The majority had single-cylinder engines developing relatively low power, though winning the TT races often, the last time was the
1929 TT. A hallmark of all Marston Sunbeams was the superb quality and finish in black with gold-leaf pinstriping. ==Later life==
