What a treat! I bought a few "old, battered, un-runnable" (my intended description) hoppers from a couple of guys online. They were slated for use as fixed scenery items on a module that "should" be finished over the winter.
Our mail lady just delivered the cars today. Oh, my, a number of them are far too good to attach like that - they will become a part of my rolling stock! At least the others, along with a few I already have, will probably get the scene completed.
Stay tuned - pictures later!
