Dear Charles,
The Dawes Galaxy you reference is akin to the same era Raleigh Super Course. Both frames have 531 straight guage main tubes. The remaining stays and forks are of a lesser grade steel. The Dawes has slightly prettier lug-work, otherwise they are essentially the same bike as the Raleigh. Both were kitted out with the same components. I seem to remember that there was a better grade model than the Galaxy. I do not remember the name. Dawes was eventually bought by Batavus of the Netherlands. I do not know if it is still Dutch owned although the name survives.
Happy Trails from;
