I recall roller blinds on the side of at least one older Solo, I'm sure.
At least one of the two had roller destination equipment on the sides and maybe the rear - (not 100% on the rear) at least when they first arrived at Darlington.
I think both gained side and rear LEDs although I may be wrong on that.
