Lol JHB, I think he's talking about the outline of the wagon, rather than having "O'Toole's Banana's" on the side. (Oh Matron!) The outline is somewhat similar, but I don't think there's a direct copy for what JHB might call the H Van. Steer clear or any with vent at the end though, I recall someone here, possibly JHB or Mayner, saying that ventilated vans didn't run here.
I have a load of old Weetabix, Ford, branded hornby vans with their logos removed, sprayed red and grey, with some CIE decals and plenty dirt and rust on them, and to my mind they look the part. After all, a wagon is a wagon, and provided the brake van and loco look the part, and there's a bullied open thrown in the middle of the consist, I doubt anyone would get upset. Or would they?
Welcome aboard John, nice to see more of the pre 80's era modellers here. Richie.
