NGC 6297 = NGC 6298. Though Swift claims that N6297 is the "sp of 2" and N6298 is the "nf of 2", there is only one galaxy here. He discovered it on two different nights (8 July 1885, and three weeks later on 1 Aug 1885), and apparently misled into believing he'd found two objects by the difference in his brightness estimates ("pB" and "vF", respectively), added the directional indicators during the publication process. At least, that is my theory -- he has certainly done that in other cases.
An interesting sidelight: Bigourdan failed to find N6298 on three nights, but on those same three nights, measured N6297 16 different times using two different comparison stars. This may well be a record number of observations by Bigourdan for a non-descript 14th magnitude galaxy. I'd be interested in knowing why he did so much work on this -- I can't find a clue in his published data.
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.5 mag galaxy. Their coded description reads E,R,BM.
