I had the preproduction CN caboose at Naperville last October. It will be the most accurate RTR model caboose on the market. It is a model of ONE class of CN cabooses. The details are of a 1950s era, wood stove etc. If you are a CN modeller you will want to sell some of your brass models. The application of CV lettering to this model would be bogus and ill advised. The CV was quite different. Allen Ferguson
