A blue, hard covered, A4 ruled book which was used at Llechwedd Slate Mines as a maintenance record book for the Rotary Converter (which was housed at Floor 5). The maintenance record book was used between February 2000 and November 2003 to record any problems or abnormalities which occurred with the Rotary Converter, as well as any maintenance work carried out. All the records in the book are written in pencil and are dated. All records were completed by Mr Elfyn Jones-Roberts, Llechwedd’s mine electrician (between 1994 and 2004). Attached to the top right hand corned of the book is a pencil on a piece of white cord.
