30590 Guardians of the Gate Louis and
Jacquelyn Trimble		 Sci-Fi 1972 1st thus Harry Borgman Note: this is the only Louis Trimble story that I have ever found that has his wife as a co-author.  Jacquelyn Trimble has another ACE volume - as J. L. H. Whitney The Whisper of Shadow (this is an ACE Gothic genre story).
30600 Gulliver of Mars Edwin L. Arnold Sci-Fi 1964 c.1905; 1964; Frank Frazetta listed as "Complete & Unabridged"
original title: Lieut. Gulliver Jones
Cover and frontis drawing by Frank Frazetta
Gulliver of Mars was originally published as ACE F-296 (1964). This edition has the same collophon with "ACE Science Fiction Classic" and uses the same cover art by Frank Frazetta as on ACE F-296. All of these criteria suggests another example of a volume that is renumbered old stock.
30675 -6 Gun Country Wayne C. Lee Western 1978 1st ACE printing
30710 Gun Rich Giles A. Lutz Western c.1955; 1962; 1st thus Gun Rich was originally published in ACE Double F-172 (1962) bound with Tom West's Battling Buckeroos.
30711 -6 The Vengeance Ghost and Gun Rich Giles A.

X. Jones Bronc (1968).  This suggests that this edition could be considered a PBO as well as a 1st ACE printing.
30795 -9 The Gun of Jesse Hand Lewis B. Patten Western 1973 1st ACE printing
30796 -5 The Gun of Jesse Hand Lewis B. Patten Western c.1973; nd; 2nd ACE printing George Gross Back cover art is reverse of front cover art.

30873 -2 Guts: An Illustrated Novel Byron Preiss Sci-Fi 1979 1st thus Illustrations by Gray Morrow and Michael Golden.
30897 -X The Gunsmith: Eagle's Gap  J. R. Roberts Western 1984 1st ACE Charter printing This is book 26 of this series.

31591 -7 The Halfling and Other Stories Leigh Brackett Sci-Fi 1975 c.1973; 1975; 2nd ACE printing Karel Thole Story story collection (seven stories)
Note the interesting blackout under the slug line for the ACE Letter-Number.
Leigh Douglas Brackett (b. 1915; d. 1978) was one of the earliest of the women science fiction (and fantasy) writers. Her first published science fiction story, Martian Quest, appeared in Astounding in 1940. She was a prolific writer in the genres of science fiction (her most recognized story is probably The Long Tomorrow, c. 1955), mystery, and western as well as television and movie scripts ("The Big Sleep" - 1946 and "Rio Bravo" - 1958).
31593 -3 Hammer's Slammers David Drake Sci-Fi 1979 Paul Alexander listed as "First Book Publication"
31597 -6 The Halfling and Other Stories Leigh Brackett Sci-Fi 1983 c.1973; 1975; 1983; 3rd ACE printing Mel Odom

31620 The Hands of Geronimo Lewis B. Patten Western c.1971; nd George Gross
31627 -1 The Hand of Zei L. Sprague De Camp Sci-Fi 1982 c.1963; 1982; Paul Alexander The Hand of Zei was originally published in ACE Double F-249 (1963) bound with The Search for Zei. Also note that the ACE F-249 version was listed as "Abridged By The Author" and I am uncertain whether this edition is an "Abridged" or "Complete" version.
Update (19 February 2013): It appears that this is the 1st ACE paperback edition of the 1981 Owlswick hardcover edition.  The two (2) ACE Double (F-249) stories were combined into one volume and published as such under one title.  This ACE edition was later reprinted under the same ACE Letter-Number (with same cover and price) in March 1983.

31847 The Jewel In The Skull Michael Moorcock ACE Fantasy 1990 1st ACE printing These Michael Moorcock fantasies are seriously out of ACE Letter-Number sequencing.
32127 -3 Trouble At Quinn's Crossing and Hell Bound For Ballarat  Nelson Nye Western c.1970; nd John Duillo Listed as "Two Complete Western Novels."  An ACE Double with a single cover.
Hell Bound For Ballarat was originally published as ACE 32725 (1970).
Someone at ACE Books was not working very hard.  The placement of these titles should not be in the 32000 ACE Letter-Number series, but rather in the 82000 series based upon the first title being "Trouble."  Oh well, it's ACE.
32270 Heavy Heavy Hangs Doris Miles Disney Mystery nd listed as "First Time In Paperback"
32575 The Hell Bent Kid Charles O. Locke Western c.1957; nd

32802 -4 Hero Daniel R. Kerns Sci-Fi 1983 1st ACE printing Cliff Miller
32815 -6 Heroes of Bear Creek Robert E. Howard Western 1983 1st thus Although Robert E. Howard is better known for the Conan adventures, it appears he had his hand in the western genre. This volume is listed as "First Time in One Volume!" I am going to put this title also in the POTPOURRI section until I get some control on this story.

37072 -1 In The Drift Michael Swanwick Sci-Fi 1987 2nd ACE printing Ron Lieberman This title is in-sequence with the ACE 5-digit series. However, the 1st ACE printing (for some reason) is seriously out-of-sequence. See ACE 35861-1 (1985). Uses the same Lieberman cover art as ACE 35861-1.
