You are looking at a beautiful clean, most likely unrun brass HO scale diesel locomotive. This one distributed by Oriental Limited and made by KMT is a set of A & B units. The Alco PA-1 is powered and PB-1 is not powered. It was bench tested and was found to be in excellent running condition. Comes with original box and requisite foam inserts.  We are The Mudlarks...we keep diggin' so you don't have too!!!!!
