Sorry for not responding earlier, it's been a bit busy over here.
I love your find Roy but gut feeling tells me it is not a hyacinth vase. When they are that small and equally wide it usually is a posy vase.
I can see it being Bohemian, Kralik too. If you look at their Nautilus range you are close. Rindskopf could be another possibility. Google images might get you a bit further.
Chris, your small pink hobnail vase looks like a Richardsons (page 51). And even if it varies a bit, if it sold it was soon copied.
