Farm Macinery & Equipment by Harrison Smith ,ex lib,with some stamps etc,otherwise a good solid copy. 514 pages,heavy item. Really comprehensive US book containing what strikes me as some really obscure agricultural gadgetry! http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=220209673254&ssPageName=STRK:MESE:IT
