Like it or not, they're here. A few years back, these were mainly showing up in European flea markets. They are now sold from mail order houses and are offered frequently on the Internet through eBay. Often times, they will be advertised as original, factory refurbished antique phonographs.
Cases come in all shapes and sizes - round, octagonal, square, beveled glass panels, etc.
No matter what the seller may tell you, rest assured that these are NOT exact reproductions. Signatures include an ornate brass morning glory horn and a unique cast back bracket. The elbow holds the horn at a high angle and has a sharp bend. Another giveaway is a crank angled into the motorboard. This is a sure sign the motor came from a suitcase portable.
