• Notes

• There are two models 83, one with the VisoGlo tuning indicator and the other without but in principle the same chassis. VisoGlo tuning indicator VG-1 is extremely rare, even in the literature it is nearly not noticed.
  
  There are also two versions: This one with a tube 78 as first detector, described and photographed in the Sparton dealers brochure - and the model with the 6A7 as first detector, according to Rider's Sparton 5-15ff and sets we have found - see photos in the link. We don't know if both were produced. See the article about the two versions and this article here about season 1934/35.
