Following is a mail from Anita Logue of Boot plc concerning the Columbine pattern. A little bit closer to the facts, although we still need to determine which of the Trippy flowers is Columbine! :?
Thank you for your recent enquiry about Chance Brothers glassware.
Unfortunately we do not have any historical supplier information in the
archives. We do have quite a lot of product literature, (price lists,
catalogues etc), although they are not comprehensive. I have looked
through the 'housewares' catalogues and price lists that we have dating
from the 1970s, and I have found one reference to 'Columbine' glassware in
a 1974 Home Ornaments and Gifts Christmas Bulletin (intended for staff).
The Decorative Glass section lists a "Fluted Plate, Coloumbine, 'Chance' "
and the price was £1.13. Unfortunately there is no illustration. For your
interest, the same list includes a few other 'Chance' items as follows:
'Yellow Rose' - Oval Savoury Server (99p), Candle Holder (£1.10), Fluted
Plate (£1.25), Sandwich Tray (£1.40)
'Lotus' - Fluted Plate (£1.13)
Have just returned from the Smethwick Heritage Centre with 90 photos :!: of some great patterns — wait until you see these! Some I have never seen before but we might have now identified Wild Rice or Cut Pearl & Willow, several floral ones mopped up, Golden/Ocean Spray confirmed, etc.
Silhouette I DID correctly identify (Sue's raggedy pom-poms

Oh how smug I feel! :twisted: :roll: :oops:
I'll relay this new information and update the web site over the weekend (but do have a Newsletter to mail out).
