Espee, I envy your ability to grow a brass collection. Unfortunately, I've got two college tuition payments hanging over my head. Needless to say, brass engines become a tough sell (though my wife does support my train hobby). I'm only a DC guy, so if I could find a brass Reading G in the $150-200 range I might be in business, but if that Custom Brass Model is the only one that made it into this country 40 years ago and very few were made, I've probably got no shot.
