For model 50-P, Electrical Research Laboratories Inc. (Erla); Chicago, Illinois:
For some time I have been looking for external sources with images of Erla model P-50, but still could not find. I have a model Erla with features similar to the P-50: 5 tubes (47 57 57 58 80 - all from the early 1930s), wooden cabinet with cathedral shape, only one wave band - BC, dial with direct vision ...) Although there are no labels in this radio, I understand these characteristics are strong evidence that this model is the P-50, so I am sending these photos for your consideration.
