NCB 0-4-0 shunter no. 11,
Photographed at Wansford, Nene Valley Railway, on 5 February 2009.
National Coal Board locomotive, presumably named after the Birch Coppice coal mine. The date "1963" on the nameplate probably refers to the build year.
Can anyone supply more information about this locomotive?
