Sterling Silver and Glass Bitters Bottle by John Grinsell & Sons, 1913.This is an exceedingly rare sterling silver and glass bitters bottle, fully hallmarked for John Grinsell & Sons, Birmingham, 1913. The bottle remains in an entirely original condition and as such the cork will require replacing should the bottle be intended for practical use. The glass bottle is of an unusual and eye catching curved form. The hallmarks to the lid remain clear, the hallmarks to the bottle top are rubbed but remain legible. Dimensions
