R30010 Hornby Hitachi, Sentinel, 0-4-0,

Founded as Ally & MacLellan, Glasgow in 1875 and then later known as the Sentinel Waggon Works Ltd, the company went through various place and name changes until in 1957 Sentinel (Shrewsbury) Ltd was obtained by Rolls-Royce. At that time Sentinel were producing steam locomotives and lorries, but the manufacturing of these vehicles ceased in 1958. In 1959 Sentinel produced a prototype diesel shunter which was operated on the military controlled Shropshire & Montgomeryshire Railway. In total 17 were produced and operated quite successfully during that year.
