If you're an uncompromising collector of antique technology, make sure to check out all my listings after you look at this one. I don't think you'll find a better, broader or more balanced assortment of technical antiques anywhere -- hundreds of listings each year, almost all of them featuring eye-popping "gee whiz" gadgetry in exceptional original condition. And don't forget, you can click this link to quickly add and then save me to your favorite seller list and eBay will automatically send you updates when I put similar new auctions online.

I'm running six no-reserve auctions this week, and they all have something in common. Each features a collectible technical antique that's not just scarce but in most cases one of only a handful of surviving examples. So if you see something that interests you, make sure to bookmark it or bid on it, because you'll likely never see it offered anywhere else again.

Here's a beautiful, working Trimm Chello Model folded horn radio speaker in a Mission pattern mahogany cabinet with pedestal feet. It's the only example I've ever seen, and I've been collecting and selling hard-to-find 1920's radios and speakers for more than 30 years. 

Condition is excellent, and the speaker is completely original, including the cabinet finish, the grill cloth, the driver and the driver cord. The driver is good, and the speaker still works.

Approximately 15" wide x 10" wide x 9" deep. Shipping weight approximately 18 lb.

I'm one of ebay's best known, most highly regarded sellers of antique radios, and I specialize in radios and radio-related items from the 1920's. I've been selling and shipping them for more than 25 years. When you purchase an item from me, you can rest assured that it will arrive 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.
