Jackson Bell was making mantle sets for Waltham by the middle of 1930. An arcticle in the June 1930 issue of Radio Industries Magazine by Dr. Ralph Powers indictes that Jackson-Bell was manufacturing not only their own sets, but also those for Herbert Horn and Waltham.

Photos provided by Rachel Lee of CHRS showing multiple views of this set confirm it to be a Model 60. The back of the chassis is clearly stamped with a serial number of 60-75480, which would indicate a model 60, as does the chassis. The tubes are the traditional model 60 tube compliment.‍‍

Advertisements of the period reinforce this information.

See Richard Gray's Model 59 and 60 circuit comparisons below.

The Model 60s:

The Model 60 Chassis was a success for Jackson Bell. It was produced in many cabinet variations under the Jackson-Bell brand, and in many house-branded sets. The set was distributed throughout the United States.

The success of the Model 59 was followed by the Model 60. There are many similarities between these two models. The most obvious difference is the addition of a second knob for regeneration to improve sensitivity and selectivity when necessary. This is an earlier technology that introduces another adjustment.

Jackson-Bell stressed the phrase "Screen Grid, of Course" in marketing Model 60s. The 24A tube is for the detector, not as an R.F. amplifier.
