No pets or smoking environment. D51 Steam Locomotive KTM? HO Gauge Model Train - As Is I received this as a gift, so I don't know the details. I did an image search and found something called a KTM D51 950 Plus Model, but I'm not an expert, so I'm not sure. Please check the photos. I haven't confirmed the operation. Since the operation is unconfirmed and the manufacturer is unknown, I'm selling it as is. Please check the photos for scratches and dirt. Everything in the photos is included. #ktm #d51 #SteamLocomotive #HOGauge
