It could be any year in the '70s, prior to '79. Grand Touring is labled on the bike I can see. I've not seen this model with anything other than Stronglight Cranks. The 1020 tubing is entry level, combined with the tubing and other parts and shape, it's not a very good bike so it really doesn't matter. Whether this particular bike preceeds the better Gr. Tours or the crank's been changed or re-labled, don't know. Hey, you yanked-it outa the garbage, it is what it is, what more can I say. It's not like it's an airloom or a costly aquisition.
