I received a few sets of NOS tubular rims. No anodizing. No marking whatsoever. Brown paper wrapping with water mark stripes and two red stripes every ten or so water marks. Rounded "shoulder" that makes me think French 60s or 70s (Mavic?, SC?). Double ferrules, maybe 350 grams, 20 cm wide. A hand written tag on each pair reads RP 45 0095 Sew Up. Any ideas?
