Freshman Materpiece radios were built in the 1920's. They were battery operated before the use of AC power. A schematic can be found here:

Value is what a person is willing to pay, maybe $50?

:My friend brought over this radio that was in her Uncle's garage attic. We have no idea how old it is or really any information about it. There are some manuals with it but nothing that im sure came with the radio. It happens to be in fantastic condition. We were curious of age and value of this radio. Any info about this would be greatly appreciated.. thanks
