Fiammes were one of the first ferruled rims, which allowed them to make them notably thinner than non-ferruled rims that had preceded them. The engineering wasn't quite worked out, and the alloys weren't what you get today, so they tended to split the ferrule rivet and the alloy was soft enough that they were rather prone to flat spots from hitting road irregularities. Because the alloy was so soft, at least they didn't actually split and fracture at the spoke holes. There's no anodizing, no finish of any kind except the decal, so they get a little oxidized with time and every drop of perspiration leaves its mark. They were definitely one of the nicest rims way back when, but I wouldn't think of them except for a classic restoration at this point. Also, they have a shallow tire bed, which doesn't mate well with most current tubular tires. As a result, you don't get as good a gluing job (you want your glue job to be as thin as possible for the greatest strength, and excess glue is detrimental to adhesion, but it's irrelevant if the tire only is glued on right at the stitching line). Frankly, the latter point would make me wary of them for track racing -- use them as a fixie and you should be OK.
As for your hubs, those are circa 1980-1982 Shimano Dura Ace track hubs, in their early configuration mostly for Japanese consumption. They have really good bearings and start out at least with a very nice satin finish. The spoke holes are drilled rather too close to the flange edge for my taste, so don't radial-spoke them, but people weren't really radially spoking much back when these wheels were probably built.
