Given that it was a Kodak Ltd paper (i.e. made in Harrow for the UK market), I'm a bit perplexed by your statement that it wasn't as easily available in the UK as Agfa papers. It may have been that the Kodak material was more readily available through the professional supply channels rather than high street shops.
I have got some in to-be-lithed pile, along with a chunk of Record Rapid. The other main Kodak Ltd papers were Bromide (not Kodabromide) and Royal Bromesko. Royal Bromesko looks like it was being aimed at Portriga.
Bromesko was phased out in the early 80s but Record Rapid lasted nearly until the 2000s so at some point Bromesko was harder to find as stocks dwindled. I think I must have tried it about the same time it was being phased out.
