I'm not sure if it would be a viable small project or not (like a Rawie, I suppose) but it would probably be helpful if one could get complete common Irish bogies such as the commonwealth bogie to retrofit to existing/future rtr and scratch/kit built instead of trying to build these individually. BTW at the risk of echoing others comments, it's an exquisite build and I'v been watching this thread with interest. Some great information regarding battery boxes and vacuum cylinders and great prototypical and model photos
