Here's what I offered to a similar discussion in August 2012:
Most original cylinder horns manufactured before 1905 will have the smaller end constructed with a straight tube soldered into the body. I believe the Tea Tray Company was the first to patent a stamped & joined small end for a horn (that's the April 22, 1905 patent we often see on horns). Others soon developed similar designs. Edison never manufactured cylinder horns (except for the Amberolas). Edison-supplied external horns were made by outside manufacturers such as Tea Tray and Standard Metal Manufacturing Company.
The fact is that not all original horns have any markings, patent or otherwise (in fact most don't). Not all original cylinder horns will have the seam running the entire length of the smaller end (in fact, very few will before 1905, with exceptions such as the small aluminum horns supplied for the Graphophones).
So how do you tell?
1) On the earlier designs where the small end consists of a tube soldered to the tapering section, check for the tube to be brass. Reproductions will often use copper.
2) Check the imaginary line from the tapered section to the bell. They should line up. Reproductions will often have a bell section that's a bit larger than the tapered section or vice versa. Look for that continuity.
3) Look down the throat of the horn from the wide end. Sometimes (but not always) reproductions will have subtle concentric lines in the bell from the spinning process. I've never seen these on originals (but good reproductions won't have them either).
4) If the horn is a larger one (more than 15" long), chances are it's an original. Some larger reproductions have been made, but I've seen comparatively few of them. If there's a question, check the hanger. If you've examined hundreds of antique phonograph horns, you'll be able to spot a reproduction hanger. Also, check #1 above. Check the construction of joints, soldering, etc. There's no substitute for experience.
