Hi Howard,
Having spent many years "hands on", working on the real vehicles that your models depict, I have to say how brilliantly detailed the models are. There is one photo of a Bedford MJ with a skyline in the background, if you looked quickly it could be the real vehicle. Well done. The 1 tonne looks the part and should be a popular model.
As with a lot of us, I started making models in small scale from a teenager with a few scratch built one, nearly all British lorries and nothing like the detail of yours. Look where it has got me....... building 1:1 scale now! :-)
regards, Richard
