To make it more complicated: Gazelle used Columbus, but not Aelle. They used Columbus for lightweigth (!) frames e.g. in 1972 (you can browse the 'gazelle catalogues' which are online, just use g**gle).
I think the frame above was re-worked and resprayed by gazelle. I've never seen an old style butterfly rear brake bridge along with these top tube cable bosses which are from the 90ties - as well as the decals.
