... I am surprised Our Bernard hasnt been in lately , i hope he is OK and he specialises in pressed glass .
JP — Thanks, yes, I am OK. We've had several weeks off camping, so the last few days have been devoted to sorting out our camping equipment and overgrown garden. While I know English pressed and I started in glass with it, it's going a bit far to say that I specialise in it today. Counting stock boxes yields a rough ratio of about 20% pressed — 80% handmade. I have 3½ shelves of recent acquisitions, none of which is pressed. Incidentally, JP, one whole shelf of the 3½ is Whitefriars, which I do my best to avoid!
Rosie — I only know of two certain British manufacturers of this fabulous Deco lighting — Hailwood & Ackroyd and Walsh. All three of the H&A pieces I've seen have been fully and boldly marked, so they're unlikely. So Walsh is a possibility, but most Walsh pieces are marked, usually quite faintly. I'm sure you would have found a mark, even a faint one. So I think it's more likely to be French. The two authorities on this type of Walsh glass are Eric Reynolds and Charles Hajdamach.
Sorry I can't be of more help,
Bernard C.
