Hi Leni are you sure its not W/Fs over the years they made a lot of jugs and i have seen so many different ambers and shapes,they and other companies used the blanks for engraving ie Watford cristal, there was a thread on W/Fs . com about bowls without bubbles i asked Ray he said they did most bowls with or without bubbles in case they or someone else wanted the plain ones for engraving like my ROAB bowl,engraving bubble glass can be difficult and costly.
