In the British-published LOOK-IN, the same magazine Bolton did a "Bionic Woman" series-based weekly 2-page comic strip from 1976-1978, This "Buck Rogers in the 25th century" comic strip:

The art on this particular strip isn't Bolton (artist Arthur Ranson, who later did two beautiful issues of BATMAN: LEGENDS OF THE DARK KNIGHT 52-53), though on a par with Bolton in its detail.
It makes me think the 1979 Buck Rogers page could have been for LOOK-IN. But my first instinct is it was for one of the Brown-Watson hardcover British annual issues.
