I don't know how long I've had this. (It's been in the house for at least 30 years) I'm not familiar with it, so I don't know the meaning of the colors or the age of the marks. If anyone is looking for this, please consider it. I think it's a rare item that's difficult to obtain now. The metal parts are dull. Decoration size: Φ3.6cm Length: 130 (65 x 2) cm Please forgive any errors due to amateur measurements. It has been stored at home for a long time. Please consider this, understanding that it is an old item and has been stored in a regular home, and please check the photos. I may offer discounts, but I do not respond to individual requests. I will delete and block any comments asking for a discount.
