【Boxed, Set of 4】Toshiba Vacuum Tubes 35C5 Vintage Original, Operation Unconfirmed

Vacuum Tubes - Set of 4
• Manufacturer: TOSHIBA (Tokyo Shibaura Electric Co., Ltd.)
• Model Number: 35C5
• Includes original box and inserts

＜Condition＞
Found during a clean-out of my parents' home.
The original box and inserts are all present.
Visual inspection shows no cracks in the glass or major damage.
The pins show typical green rust (verdigris) due to age. Please check the photos carefully for details on the condition.

One of the boxes still contained an original Toshiba Coupon from that era (see image 11).
This will be included as a valuable historical document from that time.

As I lack the technical knowledge and equipment to test functionality, these are sold as-is without any guarantee of operation.
As these are very old vintage items, please only purchase if you can assess them from the photos and are capable of maintenance.

＜Shipping Method＞
As these are delicate glass products, they will be carefully packaged, first in their original box, then securely wrapped in bubble wrap for shipping.

Thank you for your consideration.
