Amigo José Duarte,

Sobre o seu artigo em inglês solicitando uma copia do vidro (cristal) do Siera 104U:
 
http://www.radiomuseum.org/forum/siera_s104u.html


Porque não experimentar também aqui em Português/Espanõl.


Para o que deseja,  esta foto lhe envio não resolve o seu problema porque está muito irregular, mas pode dar uma indicação aos nossos amigos do
Rmorg  sobre a forma e aspecto do vidro.




Talvez se apresentar uma fotografia do seu rádio nos dois foruns em simultâneo, também possa ajudar, alguém que tenha um, a recordar de que rádio está a falar.

Cumprimentos
Mário
