Indicia title confirmed for issues #5-6, 11-16.
#10 was not published. The Comic Reader #185 (11/1980) said that Buck Rogers #10, cover dated 01/1981, was supposed to be released 10/27/1980 and carry the book length "The Madness Without -- The Madness Within" by J. Marc DeMatteis and Al McWilliams. Apparently, this didn't happen due to distribution problems experienced by Western at the time, and it was rescheduled for one of the mass-distributed three-packs, but it doesn't look like the missing #10 was included in any of these. The story was printed in German in Die Actionhelden (Condor, 1978 Series) #13, and was reprinted in one of the versions of Condor Superhelden Taschenbuch (Condor, 1978 series) #16.
