One Frank Roberge Mrs. Fitz's Flats daily with a Bat-theme.
A Buz Sawyer daily by Schlensker and Granberry from 1980. Late in the run, but I've actually seen fewer of these than I've seen originals by Crane.
And then a "Mystery strip" by Al Wenzel called "The Hackers". It's numbered #13 in the top right corner and lacks a copyright stripe. I'd guess this is an unpublished daily.
