Thank you for viewing this item. This item was found while organizing my grandfather's house. I haven't been able to confirm its operation because I don't know how to use it. In addition, the overall condition is poor, so please consider it as junk. To prevent any problems, please understand that this item is non-claim and non-return. If you have any questions, please feel free to comment. I am open to a small price reduction. Thank you for your understanding.
