This coal and limestone pit was located east of Dalry, reached by a mineral line (Blair and Co's Siding) from Dalry Junction which ran north east to the mine. The bing was to the north. The same line served Blair Mine Blair Colliery No 9 Pit, which was further east.
Probably a Blair and Co mine. Possibly later owned by William Baird & Co who owned the nearby Stoopshill Row in 1918.
