The AK 10 (4340) was the successor of the rare Atwater Kent "Radiodyne" (as the original version of this model had that name on the component ID plates). It was soon discovered that another company (Western Coil Co.) had the rights to the "Radiodyne" name and the metal ID component tags were changed to read; "model 10" in place of the Radiodyne name.

The model 10 was the most produced of all the breadboards and there were at least 8 variations including models 4217, 4350, 4490, 4540, 4550, 4560, 4600 & 4700
