Can you help to identify these frames, bikes or parts?

So far I think it could either be a carlton from the mid 70's or a raleigh blue streak (Same era).

That's sounds about right. At that time, The Carton name was owned by Raleigh. The bikes were often identical apart from the paint job.

With regards to the components I was under the impression that when Suntours cyclone models were released in the 70's they were well regarded?

In the mid 70's, Japanese components (Shimano and Suntour mainly), started to replace European brands on low end bikes, because they were cheaper but better quality. Cyclone was Suntour's top of the range but still considerably cheaper than Campagnolo.
