Overland Models 1915 & 1918 DD35 A&B unit HO scale. Not sure as to how I acquired these units but neither had a original box. Both engines appear to be new with the exception that couplers have been installed on the A unit. All of the sand boxes appear to have some tarnish on them. Both engines run great and quiet in both directions. No spare parts packages are included. Made up a box to hold both units. No longer available
