As we do not possess specialized knowledge, it is difficult for us to provide accurate explanations regarding detailed specifications or condition, and we apologize for any shortcomings. We will do our utmost to respond with sincerity until the end.

Item Condition
Exterior: Due to our lack of specialized knowledge, cleaning has been kept to a minimum. Please carefully examine the posted photos to assess the item's condition.
Operation: As we lack the environment and knowledge to test its operation, this item is being sold as-is (operation unconfirmed).
Accessories: All items shown in the photos are included.
Request
We believe that it would be the greatest comfort to my husband if these items could be passed on to someone knowledgeable who can utilize them again.
As many of these items are old, we kindly ask that only those who understand and accept no claims, no returns bid on this item.
We will answer your questions to the best of our ability, but please understand that we may not be able to answer specialized inquiries. We sincerely look forward to connecting with someone who will cherish these items.
