NGC 2351. There is nothing in JH's position, but one degree north is a group of three bright and several faint stars that could be the object he saw. I'm frankly not too happy with this idea, but there isn't much else going.
Other possibilities: this object may be a duplicated observation of NGC 2343 or NGC 2353, though neither one has a position with an obvious digit change that might point to NGC 2351.
From the General Catalogue: GC 1504 = h437. Not seen by H. "Cl, lC, double star taken" Only 1 observation on record.
Recorded in Dreyer's NGC: GC 1504, h 437 "Cl, lC, double star taken"
(Interestingly, NGC 2353, discovered by H (VIII 34) was not seen by h, and NGC 2351 (h437) was not seen by H. Perhaps these two are the same object, with a co-ordinate mistake?)
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL S.
"Another group that is home to a dozen stars. Its arrow-figure could just as well be displayed above a doorway to show direction. Seven faint stars make a point to the south, and brighter stars to the north make up the rest of this shape, with a 10th magnitude double star marking the heart of the cluster. The brightest star is about 9th magnitude as has a slight yellow colour."
