Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.
Works #3090-3094.
This is a hefty Mogul fitted with an Improved Belpaire boiler, firebox with 21 sq ft of arch pipes, and a tender of considerable capacity. Clearly, this engine wasn't meant to stay near the shops.
Within two years of this class's delivery, the Flint & Pere Marquette became the better-known Pere Marquette. At that time, the class was renumbered 210-214 and in 1902 they were renumbered once again as 223-227. 226 was scrapped in December 1929, 224-5, and 227 were broken up in 1934 (March, February, and February, respectively) and 223 lasted until January 1937.
