Those used to be considered desirable, but Grunow (General Household Utilities) was more or less an orphan brand, and they built and sold a lot of the 12 tube Teledial models, probably because the price was under $100. I think that the model with the P-P 6L6s driven by 6F6s may have been the 15 tube model, it also had three speakers. There was also a less common variant with the 12 tube chassis that had a door over the control panel. In any event the one you have is the same model they pitched in an ad featuring the late Shirley Temple (Black).
One issue that these sometimes run into is an open broadcast oscillator coil, so check that over. I think that Bob Anderson has a non Teledial model with a very similar chassis and front end and he may have had problems with that. These sets had separate oscillator and mixer tubes, and a tuned RF amplifier stage, I think that they may have also had an AFC but don't quote me on that. One problem I noticed with Bob's Grunow is that, unlike a contemporary Philco or RCA model, it did not have a very good band spread, which is a shame. Maybe the Teledials were different? One thing is for sure, they beat a brand Z model for dial appeal.
