I know the Drey jars aren't high dollar jars and not all that collectable but I have an odd one. It is an unlisted RB 834 pint with 1/2 bosses and no neck bead. To top it off it is an unlisted color, light green with amber swirls. I think the neck configuration is the same as RB 300 variation number 1, Ball Sanitary Sure Seal. The neck configuration is not the one Schram patented 21 Sept 1920 and is perhaps an experimental style. Anyone have any ideas?
