The best known versions of this instrument were marketed by Harmony – Model H75 (1960 – 1972, fixed tailpiece, yellow sunburst), Model H76 (1965 – 1972, Bigsby tremolo, yellow sunburst), Model H77 (1963 – 1972, fixed tailpiece, red sunburst) and H78 (1965 – 1972, Bigsby tremolo, red sunburst)
Versions were also marketed by Airline, Heath by Harmony (Heathkit), Regal, Silvertone, Sears & Roebuck and Truetone.

The pickup type shown here was fitted on a small proportion of CMI guitars.  It has an integral chrome bezel, six individually adjustable slotted pole-pieces and four slots with a gold infill.  It was manufactured in one height only.  Different pickup heights for this particular pickup were achieved by the use of timber bases of different heights, flat on top, to match the pickup base and concave on the bottom, to match the guitar.

 

Silvertone Models.  These guitars are fitted with either the pickup type shown above or a chrome D-grille pickup with a silver foil infill and an integral chrome bezel, as shown below.
