I've had this snail for 10-15 years and couldn't identify a maker or country of origin, but finally found a very similar snail with a Murano label on it. Another member suggested it might be corroso glass but we both lack the knowledge to judge if it is or isn't. Can someone who has that knowledge give an opinion on what it is? Bob the Snail is 6" L x 3.5" H x 2" W with no signature or other marks, no mold lines and fairly heavy for its size.
