Bought a roll of Oriental Seagull when I was in Japan last year. It is a very cheap BW product that, from what I have been able to research about it, is a Harman (Ilford) made product that is exclusive for the Japanese market, and it is NOT a rebranded Kentmere 400.
Film edges are marged with OR NSG 400. Film doesn't curl much at all, kinda like latest generation Ilford products.
Every film that is not a rebranded Kentmere or Fomapan interests me of course, so gotta try it. Shot this roll with the Lomo LC-A while spending New years in Budapest. So here are some street photos.
General feelings are that this is a quite grainy, old style emulsion. Latitude seems fine, film speed is not exaggerated, it is probably very close to actual 400. One roll is not enough for a proper review but, so far, I like it. I'll pick up some more rolls next time I'm in Tokyo.
