According to the HM video in my previous post, the teaks don't suffer any of the faults in the previous two liveries.
Hatton's have the ones from the dodgy batches marked very clearly.
The only complaint that the HM guys had was that they left the coaches out in the sun and one started melting.
Still, at two thirds off, even if a few bits fall off, it's like a 99% completed kit for less than Murphy Models OO Gauge coaches go for.
