My belief that these towers did not sell well was based on two observations. First, they seemed to be available on the etailers web sites for a very long time, several years. And second, my LHS has an Alto tower sitting on his shelf that has been in the same place for four years now, and he is in Pittsburgh. This led me to beleive they did not sell well. None of this is based on any real sales data or industry insider information, just my observations. If they were a sucess for NSA, then that is great to hear. Being a Conrail/Pennsylvania RR Pittsburgh area modeler, anything Pennsy in N scale is welcome and will most likely be purchased by me.
