What Ho! I was hoping you clever chaps may be able to help me with the identification of this bowl.
It is lead crystal, 5.5" across and has a ground pontil.
The outside of the bowl has very fine threading which spirals all the way round and isn't concentric rings. The threading very accurate and must have been done in some sort of jig. The superb pattern is made by flat long bubbles in the glass. How they made this I couldn't imagine!!
The pontil is hand signed with a stylus and looks like it starts with 'B' and ends in a 'L' , I could be wrong here of course!!
Im not even sure of it date, although looks similar to glass from the 20s-30s.
Any help with this puzzler would be most appreciated, regards Wolfie
