• Notes
• Radiodina Tipo 7. Radio-ricevitore in scatola di montaggio, venduta nel 1925 a lire 1.900 (bollo governativo compreso). "Guida pratica AR II" indica circuito supereterodina - dato che risulta però da verificare con certezza in quanto la prima supereterodina commerciale fu introdotta appena un anno prima in USA.
  Sold as a kit for 1.900 ITL. Although the book "Guida Pratica AR II" lists this as a superhet, this is unlikely, since first commercial superhet was sold in 1924 - just one year before this.

• Price in first year of sale
• 1,900.00 ITL
