Davol Duraglas Nurser Baby Bottle. Circa 1940s. As seen the rubber in the nipple has harder and a little flacking around the edge where it applies to leak cap and screw cap to screw onto bottle. Actually most of these nipples melted and are pinched and brittle or missing entirely. Over all this nipple is in fair shape. No chips or cracks. Selling this item for a collectible. Do not use on human life could be hazardous to humans. Enjoy as a fantastic collectors item. This item is well packed in a box size 10 X 9 X 8 inch and has a total boxed weight of 1 pound 5 ounces.
