| seller note | Vtg 1940s Tel Devices Twin Fone Telephone Phone Attachment Hearing Aid Accessory. A vintage 'Twin Fone' phone attachment made by Tel. Devices Co. of New York. From what I understand, it attaches to a vintage telephone and then the user can listen to a call from both ears. Comes with an extra plastic piece, not sure what it does or if it originally came with the phone attachment or not. |
| comment | This con tube is rather specialised but designed to aid the deaf. There is a small accessory I can't specify, I guess an adapter. |
