Thanks very much for sharing this interesting find with the forum.

Enjoyed following the earlier thread and now with this one we have much better imagery to work with.

Fitment of the Lyotard 460D pedals is something one does not often see on an Italian machine. Wonder if perhaps the cycle's owner was unable to fit their feet between the spurs of the Sheffield quill pedals it may have come with. Some of the Sheffield quill patterns are quite narrow. One check which could be made is the thread. If they are metric that would confirm non-originalness.

The right pedal looks as if it may be bent. You might wish to check it. Cannot tell for sure if it is at the spindle or at the body. Looks more like spindle. Its reflectors are Cibie.

Odd to see the SR Custom handlebar stem paired with a 3TTT bar. This is a poor fit as the stem has a clamp size of 25.4mm and the bar a centre dimension of 26.0mm. Note how the stem's binder ears appear to be prised apart. Potential safety issue.

Regarding the Prima marque, checked a couple of extensive marque lists where it turns out not to appear. This may tend to support the idea that it is marque created by/for a distributor, importer or retailer. Online searches do not work well as all of the hits are small p ones rather than large P ones.
