G-BVKA Red Stripe
I think 16 years of mish mash since BD had a uniform fleet. I would say that the delivery of the above B737 with the red stripe, followed by G-BVKB without the stripe, then G-BVKC with a different width of stripe started the whole shebang. Then we had the dark colours, I wonder was everything painted in those colours before we saw the BMI launch?
G-MEDM does look quite shiny actually !
