MrKB is a self employed mobile mechanic & welder. Pretty dull stuff but it pays the bills. Hes bloody good at what he does though and I often joke with him I'll send him out to Marbella to work for Jock at "The Garage" as H always diagnoses the works & how to fix it on there before the narrator or Jock say....thats without even looking at the car! 
He tells me he's going to be a fisherman when we sell up and move out to Cape Verde once our house out there is built.
