Hello everyone, I'm an Italian collector of 78 rpm records and gramophones, over time I have purchased many lyric 78, among others a columbia grand opera sung by Suzanne Adams, the song is "Primtemps nouveau", the disc is in good condition, I know that it is a rare piece, but I would like to know its value, and possibly trade it with others of my interest. I have many other, by Caruso, Fernando de lucia, Tamagno, Salomea Kruscenisnki, ecc, ecc... I am looking for either replacement parts for Victor phonograph or discs of Italian swing.
thanks
