  The COMPTEL experiment aboard the Compton Gamma-Ray Observatory (CGRO) has
observed the gamma-ray blazar 3C 279 several times between April 1991 and
September 1995. This paper reports on a consistent analysis of these
observations using the most recent COMPTEL data analysis tools. Detections and
non-detections of 3C 279 along the CGRO-mission indicate a time-variable
MeV-flux. Spectral variability is indicated as well, however can not be
significantly proven by spectral fitting. The average MeV-spectrum of 3C 279,
as measured by COMPTEL over the four-year period, is consistent with a photon
power-law slope of about -1.9. This spectrum smoothly connects to the
simultaneous 30 MeV to 10 GeV spectrum obtained from an analysis of the
combined EGRET observations. No spectral break is required to fit the
time-averaged MeV- to GeV-spectrum of 3C 279.
