How to date a French telephone ?


Telephones supplied by the networks are always identified on the back of the device or on the earphones or the receivers by letters and figures inscribed in small oval tablets.

For example "LT", "08"and "92" :

"LT" means Ligne Téléphonique.

"08" means the month of construction, here august.

"92" means the year of construction, here 1892.
