:rah: I was delighted to find this lidded box this morning (ok, I am probably the only person who collects plain opaline and not high end stuff at that :ooh:) so, I'm wondering about era? it looks possibly 30's/ 40's would I be right? and where from? any information gratefully received as all I can ever find on opaline is fancy doody expensive and mine clearly isn't really

Oh, it's chipped.... of course

and it is mould blown with cut and polished rims 5 1/2" wide and 2 1/4" high approx
many thanks!
