Copied from Minerva website (hope Chris doesn't mind !)
We have to report that when the Class 14s arrived yesterday, we saw that, despite our best efforts, the cab colour that we modified from the decorated sample was still not correct. It still has too much green to match the prototype we are seeking to accurately model.
We briefly considered whether it was close enough, but have decided not to release the models in their current livery. Minerva has always endeavoured to offer accurate models and we hope that you understand the reasons for our decision. It is frustrating for all of us, but we believe it is the right thing to do.
Our factory are going to produce replacements as soon as possible, and as the cabs are only secured by four screws, allowing them to be lifted off to fit crew, it is a straightforward task to fit the new cabs.
We hope to have the replacement cabs in about 8 weeks, but will update as and when we have definite information.
