Up until 1903, the cylinder market in England had been dominated by Edison Bell, whose patents gave them control. Once their patents expired, the market was opened to new competitors such as Sterling Records and Clarion Records.
Like the contemporary Edison Gold Moulded Records, Sterling Records were classed as 2 minute cylinders (100 threads per inch), but were around ¼-inch longer so had a little more capacity.
Sterling Records sold well with the first million cylinders sold in the first 22 weeks of business, and the cylinders were well recorded and made. However, they were discontinued in 1908 when the Russell Hunting Record Company went out of business.
