Langhaugh & Beaubow, most likely Sanyu Glass, early production so late 60's to early 70's.
I have about 30 pieces in this colour way which is quite prolific by the company, but the style and shapes that turn up still amazes me.
Beaubow's piece is definitely not run of the mill and is 'high end' for this company. Langhaughs would be more highly produced as I have seen the shape a few times over the years. But still desirable.
I have my Sanyu Glass box of glass from the storage unit and will list the pieces here in due course. Once I clear out some Murano pieces.
