Lovely pics tim,the old pit village where i live was demolished mostly by a 951 and a 955,the 955 had a purpose built rsj steel beam with a flat plate on the end for pushing down buildings,the demolition company was called limbro demolition and i spent hundreds of hours watching it as a boy,sadly i took no pics as i was too young ,but i have a local history book with a picture of it in action and will post it along with a few others.
