(1948 - 7 inch)
This set was available in many different cabinet finishes, and in both a table top version (shown here) and as a "suitcase" style portable. 7 inch electrostatic sets of this sort were considerably cheaper (about $200) than the 10 and 12 inch models, which cost around $400. Here are schematic diagrams.
