If you look inside http://trac.osgeo.org/gdal/browser/branches/1.11/gdal/ogr/ogrsf_frmts/mitab/mitab_spatialref.cpp you see: { 6277, 79, "OSGB_1936", 9, 375, -111, 431, 0, 0, 0, 0, 0}, The shift values were replaced in GDAL some time ago, but obviously not in the mitab driver. Keep in mind that EPSG:27700 in the original EPSG definition does not obey any ...
