History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 6693 is lost. There are only faint stars in the area of Marth's position. The RNGC claims the object to be a star, but I see no particular single, double, or multiple star around that might have caught Marth's eye.
Of the nine other objects that Marth found the same night ("1864.59"), two bracket N6693 in RA, and are at similar Dec's: N6688 and N6713. Neither has a large offset in Marth's position from the modern positions, so I have to presume that N6693 is also unaffected by any systematic error.
Barring a large digit error (e.g. 1 degree, 10 minutes), Marth's object is probably gone forever.

Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads * S.
