Thanks for the pointer. Whilst i haven't found my example i did learn a lot searching through images of both those companies. Hineri, of which there is not so much online, frequently seems to mimic Czech glass, Skrdlovice in particular, or perhaps they were first?
Kamei is interesting too. Quite acid colours but kind of cool. Another label that i found along the way was Sanyu. They also seem to have produced a lot of glass which could easily be traded as Czech or Murano. It was so helpful of you to mention actual production names, thanks again.
