Those are typical boom era wheels, found on many upper entry level, French models such as the ubiquitous Peugeot UO8. They were decent for the era, though heavy, and while the rim serrations improve braking, they don't perform as well as aluminum in this respect. The rim chrome is surprisingly good, but there's a fair amount of rust elsewhere. For me, the deciding factors would be the condition of the cones and races, and whether or not the spokes will turn. Even if the wheels are unusable for one reason or another, there are always people looking for these rims and axle assemblies, in good condition.
