Téléphones sans duo 2 Philips D2651B

Selling two Philips landline telephones that usually pair with the Philips D2651B (which is in the last photo and which I am not selling). If you purchase them is because you have the base and wish to create a mirror landline or for parts. The telephones work well but on their own, I am not sure they can work properly (although I am not sure).
