Telechron emerged from the War wholly owned by General Electric but in great shape financially. It expanded its operations and hired lots of new workers. That's the good news.
The bad news is they figured out how little Americans would accept in terms of style and quality. One can immediately began to see a drop in new designs and although mechanically, the clocks were still sound, new models were designed with less expensive materials. Take the dwindling 3 series offerings: a tiny tambour, a silent version of the 7H103 and three cheaply redesigned versions of older models.
More focus was placed on kitchen clocks, previously only a sideline. These years were a boon to the housewife, offering her a wide array of affordable labor-saving devices. Dependable electric time was just one more.
There was also bevy of new alarm clock offerings and they were more in demand than ever. I believe Telechron figured the small, additional cost of alarm parts didn't warrant marketing silent versions of table clocks. Sadly, the 6B17 is the end of the line for the 6 series. The 5 series is already extinct by now (don't let on I told you, but it stages a bizarre comeback in a few years) and we're seeing here the virtual end of the 3 and 4 series too.
The company did have an ace in the hole: The clock radio. The 8H59 Musalarm was the first dedicated clock radio ever and sold like hotcakes. Telechron also marketed a variety of radio and appliance timers that did their part to perform some post-War magic for America.
