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.
