Hmmm, I remember buying some from Freestyle in the early 1990s that, as I recall, they said were Ilford. Maybe that's the 'in the UK' part on the announcement. Whatever they were, the were by far the best I've ever seen - thick black metal body, nice coppery caps, sturdy reels, good felt, tough and secure as hell. Obviously would have lasted forever, maybe with felt replacement after a decade or two....
Too bad I had to leave most of them in Belarus (I'd lived there a year, and didn't have room in my luggage when I left - though would have if I knew I'd never see such quality again!). Anyway, I just bought a bunch of cassettes on eb, so look forward to seeing what Ilford/H. make next time I need some! I can only dream they'd be as good as those I had 20+ years ago!
Ilford/Harman continues to be one of the brightest spots in the too often dark world of photography.
Oh - I just read the full posts on this and saw the note about not reloadable; so I'll limp along with the flimsy metal ones I can get for now. Anyway, I can't get enough of HP5 et al., and must try some of that Kentmere soon... loaded into my flimsy Korean cassettes.
