Hello,
I have an early '70's Dawes Galaxy. It's original, down to the functioning plastic Simplex derailleurs and steel crank. But someone in the past swapped the rear wheel for a generic steel unit with a Shimano cassette. It works fine but I would like to put an original rim and cassette on it.

Does anyone know what cassette is original for this bike? I have a Maillard cassette with steel rim, in my parts bin, probably from an old Raleigh Record. Some of the Galaxy components also seem to be shared with the equivalent Raleighs of the day, and am wondering of a Maillard cassette would be correct.

Thank you,
