Frank â€” Stevens & Williams changed name to Royal Brierley Crystal in 1931, although they may not have used the name Royal Brierley in the USA. You may recall my speculation on the previous Glass Message Board about the name Vernay
(see a 1939 example
), which could have been a RB trading name in the USA, or the name of a S&W / RB product range, USA only, USA and Canada only, or worldwide.
As regards Alabaster
, it was made from 1914 (Jackson, 20th Century Factory Glass
) to the 1930s, so should almost always be attributed to S&W / RB as it is usually impossible to date it within this production period. Barbara's fine example dates from 1922, so can be positively attributed to S&W as it was made before the change of name.
