This is another doorbell model. I find it in Rua dos Ferreiros in the door that I put in the second photo
I find this doorbell in Rua dos Netos, wich is near the Funchal city center. That´s an old building where I think no one lives there.
I found this "marriage" of a door bells in Rua dos Ferreiros (Ferreiros Street). The new interface is very simple. Perhaps it makes more noise, but is much more ugly and with no art.

Encontrei este "casamento" de campainhas numa porta da Rua dos Ferreiros. A nova é muito simples. Talvez faça mais barulho, mas é muito mais feia e sem arte nenhuma.
