Here's a very scarce Type TRU Ace Concert Receptor manufactured in 1922 by the Precision Equipment Company in Cincinnati, Ohio. 

Though the TRU Concert Receptor was -- at $50 -- a somewhat pricey, low production receiver that bore little outward resemblance to the hundreds of thousands of inexpensive regenerative radios that would eventually follow it out of the factory of Precision's crosstown rival, the Crosley Manufacturing Company, the TRU was in fact the driving force behind Crosley's 1923 acquisition of Precision. Precision possessed an Armstrong license for radio signal regeneration, and Crosley very much wanted one. 

Condition of the TRU is good, and the radio is one of only three examples I've seen in the 35 years that I've been buying and selling radio gear from the 1920's. There's a splinter of wood missing along the vertical seam of the cabinet's rear right corner, but the radio is otherwise complete and correct and retains both of its metal tags on the top side of the lid. 

Tuning coil is still tightly wound around the form, tube socket and rheostat are undamaged, UV-201 tube has a good filament.

Despite its relative simplicity, this is a large radio. It measures approximately 17" wide by 7" deep by 7" high. Shipping weight, properly packed, will be about 15 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 phonograph from a farm tool), 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.
