IC 3183 is a star. I had written earlier that this "is a double star, perhaps connected to another star on the original plate by a defect or random grain noise? Schwassmann's position is close to the double, and the other star is less than an arcminute away. His description reads "vF, cS, perhaps 2 **, delta :". There is only one double in the area -- thus my lingering doubt about this."

This is wrong. The star that I took for a double is, in fact, single. The second object, if that was what I was looking at, is a galaxy too faint to have appeared on Schwassmann's plate, taken as it was by a 6-inch telescope. I must have had some notion of this as I have only positions for the two single stars, not the galaxy.
