Here's a Federal Jr. crystal radio manufactured in Buffalo, NY in 1922.This is a beautiful radio (large for a crystal set -- almost 10" high), and it still works work well if you've got the a proper longwire outdoor antenna and a good indoor ground connection (not household wiring).

Condition is exceptional, almost like new. In fact, this is probably the cleanest original Federal Jr. that's ever passed through my hands.

Bakelite top is immaculate, with no cracks, no chips, no damage. Glossy original black enamel on all sides of the metal cabinet, with only a few minor marks. Excellent nickel plating everywhere, with no rust, no pitting, no problems. Crisp original cabinet litho that's legible everywhere. 

Original crystal detector is clean and correct, with a sensitive crystal and catwhisker.

Inside, the chassis is pristine. Original double slide tuning coil, original tuning condenser, original Federal antenna condenser, straight original wiring, etc.

Federal 53-W headphones are working (both drivers are good), and the driver cord is electrically viable. 

In the video above, for the purpose of demonstration, the radio is connected to a 1920's two-stage tube amplifier (powered by an ARBEIII), and a vintage Burns horn speaker. Only the radio is included in the auction. The amp and loudspeaker were used simply to demonstrate the functionality of the radio, which typically would be used with a headset. The radio will of course work with the Federal headphones that are included.

Shipping weight, properly packed, will be about 10 lb. 

I'm one of ebay's best known, most highly regarded sellers of antique radios, and I specialize in radios from the 1920's. I've been selling and shipping them for more than 25 years. When you purchase an antique radio from me, you'll receive a radio that arrives safely because it's been carefully packed (by me, not by some well-intentioned but nonetheless confounded, doe-eyed teenager working at the UPS store who wouldn't know a radio from a radiator), Sure, you can probably get a lower price from Joe and Janet Barn-Find, but when your "bargain" arrives broken, and without any hint of how you might be able to put it back together, you'll realize that you really do get exactly what you pay for.
