Thank you for viewing. Model Train HO Gauge S.Soho&C o. BOX4894 LosAngeles Railway Type M- 1 I lack specialized knowledge and cannot answer questions about the product. Please check the condition in the images. Please purchase only if you understand. Operation has not been confirmed, and the main body shows signs of discoloration of the metal in places due to aging. Please refrain from purchasing if you are looking for a product in the same condition as new, as it has been in someone else's hands once.
