Hi Rob,
yes you're right, from memory the "Redscaff" word was red. Its funny how memory plays tricks with you, but I also seem to remember some vans did not have the full black background, as in photo you referenced. Some had an all white background with the word having a 3D black shadow. The owners of the company must of had shares in Bedford, as about six pictures on from the link in your original post, the Bedford truck, sorry, lorry was also belonging to Redscaff.
