Gentlemen,
Actually one of my non Tin Plate favorite new Box Cars is made by Menard's, their simple classic Military Ammo Box Car is just fantastic, being a conservative kind of military guy this was a welcome addition to my US Army Special Forces Train.
David one of our OGR members, sold me a serious Atlas PRR Insulated Box Car, which is really quite nice also, great looking Atlas PRR Tuscan Box Car.
