IC 2773 is one of two stars near Wolf's position. Neither shows well on the print of the original plate. The fainter star is within 3-4 arcsec of Wolf's position, while the brighter one is northwest by about 15 arcsec. Wolf notes his object as "v. irr., diffic", so it could even be both stars. It is also possible, of course, that Wolf's position could be wrong, the victim of a typo or a reduction error.
I've given positions for both, and suggest that this is another object to examine on the original plate.
