David, Very sorry that these did not work out. Not sure why. Bowser had marketed niche diesels for some time (Alco's Baldwins) and it looks like they manage to make it work-Perhaps more HO'ers are interested in these that N scalers-Maybe N scalers want mostly more modern diesels? I am sure manufacturers have some survey data, but they probably would not share it. Looks like Arnold had trouble moving their U25C as well-I was hoping that would lead to a U33C an U36C but I guess that won't happen either.
I will look into placing orders for FUD shells after the holidays. The Hi Adhesion truck frames are great!!!
