Replacement windows for Walther's N-scale New River Mining Company coal tipple kit. The kit provides 28 window which are difficult to modify or paint. The replacement windows sit closer to the surface of the structure's outer walls for a more realistic look. The replacement windows only have 6 panes instead of 9 which give this popular kit a less "familiar" overall look. 40 windows are provided with 30 in the closed position and 10 in various open positions.
