The bike seems to be in good shape with a little rust on the edges but other than that...sound. Is this bike worth fixing up? (New tires, grease, brakes?) I have no idea what it may be worth or if I should even bother getting it rolling again.
I'm far from an expert but I'll say it's certainly worth cleaning/tuning up. There are 3 models in that ad but at the least the bike would be made with 'straight gauge 531' (type of tubing) totally decent frame. Pics of the bike in question are needed before anyone with real knowledge will weigh in though.
Good find. How did you date it to '74? If you clean it up, don't throw away or change anything. How's the paint and decals? Nice bike. Oh and, welcome to the Forum.
I wasn't serious about wanting it. Just trying to "encourage" you to get it if you hadn't already, especially if in nice shape. Check out Sheldon Brown's website. He has a few short paragraphs on the Falcon Merckx bikes.
