This machine was called the Iron Jack by the coal miners in the UK North Staffordshire National Coal Board area, it was the first computer the coal board purchased and used for payroll for the 25000 employees in the area, I need to identify it, exactly the picture was taken in 1958 . It could be a 650 but the control panel does not look the same as some 650 pictures. It was replaced by a 1401 which is complete and we have that. I would like to get one of these hence the need to identify it.
