Hi,
I've looked at the Nazeing / Elwell stuff and I have a few bits of it - my bowl is nothing like them. Glass / colour / everything!
With regards to the other stuff I meant the other un-ID stuff does seem to be older than my bowl - someone -was it Nigel? said they had been around for quite a while and might even be contemporary with the Ysart stuff, i just don't think my bowl is that old - maybe 80's but just guessing.
Maybe more will turn up - I'm still waiting for Gary Millerart to have a look to see if he has any opinions!
