I bought this drinking glass in the charity shop today, only 20p. It has the exact same printed image as Keith shows in reply 13 that is on his Webb Corbett style weight. Did Webb Corbett ever make glasses such as this?
The glass is very light with no ping when flicked so assume soda glass. There is a knob in the base of the bowl above where the stem is attached and it has an electroplated type gold rim. 11cm tall.
Would this be copper wheel engraved, then?
[For the engraved weights] I assume large manufacturers would use copper wheel engraving and it would only be small workshops:hobbyists that use Dremel type tools (drill engraving).
