Maybe the choice of a 66 offering was due to taking on the former Hattons offering, with the intention of adding a few tweaks?
Purchasing the tooling makes good business/economic sense
It was already an excellent model, I'm pretty sure Accurascale will deal with the original issues before the model is re released.
Excellent news that you're on project team and are providing feed back to KR models.
I've recently purchased the Bachmann D213 Andania and can conclude that it's a fine model.
An Accurascale 40 will most likely follow at some stage, fingers crossed!
