The combination to a Manifoil Mark 4 combination lock on a ministry cabinet in North Wales had been lost. We were asked to open the unit as they were disposing of it and needed it emptied prior to it being let off site. Due to the nature of the facility we were not allowed to take photographs and had to be escorted at all times but we got the job done.
