IC 3223 may be a defect on Schwassmann's plate. He says of it, "vF, pS, alpha :, delta :, am[ong] 3 vF sts." The three faint stars are clear on the sky today, and two of them have been taken as the IC object in various lists. Ames picked one (but did not give a position), Wolfgang has a position for his choice, and I have all three listed in the main table. I also give a mean position for them, suggesting that Schwassmann's object, whatever it might have been, is somewhere nearby.
The problem, of course, with chosing any of these stars is that Schwassmann mentions them explicitly -- his IC object is not any of them. If his plate still exists (it seems doubtful that it does), we could check the object there.
