yes, wish I was a cunning linguist like Ivo.
Harbridge Crystal Co., Ltd. - the following may be of interest or help regarding this post, and is taken from Nigel Benson's text and abbreviated somewhat in the interests of saving space ......
Short-lived firm from 1924 - 1966, with break for WWII reducing their production time even further. Made glass blanks for others initially, but their production ceased in 1955 (leasing space to Webb & Corbett's) subsequently concentrating on decorating work. Two years later W.& C. absorbed them. In common with other smaller Stourbridge manufacturers, little is known of their output, which overshadowed by larger major glass companies. Did make much traditional material, also some contemporary and stylish designs equal to some of the better known companies of the period.
Acid backstamp should read HARBRIDGE
