John - Like all British designs, they’re a very different design to anything Irish; in truth, Provincial Wagons kits are the only show in town.
Before Provincial had ever announced their cattle wagons, I bought a couple of Dapol, Hornby or Bachmann ones - two out of those three anyway - to see what could be done with them, but unless very serious compromise is acceptable, you’d need the Provincial ones. Post-1960, they’re about the only rail vehicle, passenger or goods, which would have a rake of wagons of the same type, before block trains!
