Märklin HO Gauge 7339 Manual Main Signal Structure with Original Box and Auxiliary Insulated Rail I have confirmed the locomotive runs and the red and blue signal lights illuminate during a power test. However, as this is an old item, maintenance may be required due to poor contact or mechanical issues. Using the auxiliary insulated rail eliminates the need to insert insulating paper in the signal isolation section. It will be shipped in the original box. I am selling this to organize my collection. The items included are the signal itself, the auxiliary insulated rail, and the original box. The background in the photos, the locomotive, and the rails are not included. This item has been stored for a long time after use, but the condition and appearance are good. Also, the original box is in relatively good condition for its age. Please understand that this is an old item before purchasing. Please refrain from purchasing if you are sensitive to condition or expect new-item quality. Recycled materials will be used for shipping. I hope that those who understand this will purchase the item. #7339 #Signal #marklin #maerklin
