IC 5149 = ESO 466-G027 = MCG -05-51-033. Though Swift's position is typically bad, he notes that a "6.5 mag star same parallel follows 63 seconds." This positively identifies the galaxy as ESO 466-G027 rather than the somewhat brighter (but further from Swift's position) ESO 466-G024.

Observing in September 2018, Steve Gottlieb concurs, saying in an email on 18 September,

... It's certain that IC 5149 = ESO 466-027, based on Swift's comment "...6 1/2 mag star same parallel follows 63s". But this implies he missed ESO 466-024, which I found somewhat more prominent in the eyepiece and is only 11' away, in the same eyepiece field! So, IC 5149 and perhaps IC 5239 (which see), are just two examples where the observer, working close to his visual limit, notices one object but misses a slightly brighter neighbor. Just our imperfect eye/brain combo.

I couldn't agree more.
