SC 207: A second photo, from the collection of Henry Miller, is added.
SC 297: From the collection of James Everett Parks, a good photo of this chaser.
SC 301: A new addition to the collection, also from the collection of James Everett Parks.
SC 329: I recently picked up a canal bulletin from 1917, and found the photo of SC 329 – the one shown in the microfiche image posted earlier – on the back cover. The image on the bulletin is in better condition, so a scan of it is added.
