Micro Ace A9510 Steam Locomotive D51-906 Standard Type, Peace Mark The body is very clean. It appears to be unused. The case is from KATO. ◇◇◇ I apologize, but I do not have expert knowledge regarding model trains, so I cannot answer questions about operation or details. I understand that it is a precision model. When shipping, I will wrap it in cushioning material and send it with care. I am also listing other N gauge items. Thank you very much. ◇◇◇
