This is a Regency TR –1 transistor radio. A new battery was purchased and put in it and it turns on and works. I could only hear static as I don't think it was picking up any local radio stations. The gold lettering for the word Regency is a little bit worn on the actual radio but on the leather case, it is in perfect mint condition. I've included a picture of the box that the new battery came in. I do not know much else about this radio. It was given to me by an elderly neighbor of mine who has since passed away. I am unsure if any work has been done to it. I tried to take a good photo with the back off so you can look at it. If you have any questions, please ask.
