this No. doesn't appear in the 'Blue Book' - which is the Glass Asscociation check list of Registration Nos. from 1908 to 1945. However, the 781 series of Nos. do cover a likely period for the registration of such pre war articles as trinket sets i.e. February to March 1933. Tell us which Nos. are you certain of, and we may then be able to determine which No. it is supposed to be, possibly - there aren't too many in the series, something like sixteen I believe. Where are you reading the No. from, by the way - do you have these sticks?
