70's 700C wheelset
I was digging around in my old stash of parts in the attic yesterday and came across a set of wheels, they're Weinmann concave rims with Maillard low flange hubs, with Hutchinson 700c-22 tires on them. They were taken off one my many bikes back in the day, by the looks of them they were never ridden. The only thing is I can't remember for the life of me what they came off of.
What bikes in 1977/78 came with concaves in 700c and Maillard hubs? I had a ton of Motobecane and Peugeot bikes back then, a few Raleigh's and a few Schwinns, but I don't remember these for some reason.
They're in mint condition, I had stuffed them in trash bags and hung them in a closet along with a few other sets, they got hidden over the years by the piles of other stuff up there. The hubs are dated 1977.

1978 Raleigh Super Course had this exact wheelset in the narrower A124 width.
I remember having troubles with mine because the factory used a grinding machine to level the ends of the too-long spokes, which left numerous tube-puncturing burrs along the inside of the rim, which even the narrow rim strip couldn't cover.
Bike got stolen about the time that I had finally solved the mystery-flat problem.

Motobecane stuck with 27" throughout the 70s for their clincher bikes. In the last year ('79) they introduced 700c for the Grand Record only.

Some of the earlier Raleighs (including the Competition) used wider A129 concave rims that often had QC problems with the braking surfaces.
This was a problem with other OEM rims sourced from Araya even, where bulk-pricing pressures led rim producers to too-hastily hand-grind welded rim seams. Note that the aftermarket versions of these rims showed no such problems and had other changes to their features such as eyelets and anodizing (or not) and whether welded or pinned. I would examine the braking surfaces before spending any time reconditioning any such wheelset for a decent bike.
