The top iron is a Steam-O-Matic B-200. (It appears on the cover of my book, Streamlined Irons , which can be seen at www.streamlinedirons.com). It is a rare version of the B-200, in that it does NOT have a black painted handle. The iron below the B-200 is the B-300: notice the difference in the way the front of the handle interfaces with the body. Also, there are no polished streamlines on the 300. (If you click on the photos, you'll get a larger version and be able to see the details.) The B-300 is an extremely common iron, which came out after the (much less common) B-200.
The iron below is a C-100 and, so far, it is unique. Its mysterious aspect is that the interface of the front of the handle with the body is from a B-300 and the body itself is from a B-200. If you have a C-100, I'd like to know about it.
