I agree on the B&O P7D in both classes and the T class as well. 
The P7D is one of those must haves for any B&O modeler but no one except Key Brass has even attempted them in recent years.  It is very hard to justify spending upwards of 500$ on a brass P7D not knowing if that thing will last 10 years or 10 minutes.

Come on Bachmann!!!!!!!

Any word as to when we might see the n scale Berkshires?  I see that Walters has moved the date to unknown.

Thanks,
