This is a great item, a 1-37 Parke, Davis and Co. Ltd, Walkerville, Ontario GLASEPTIC NEBULIZER in the original box with the original printed instructions. The instructions are dated January 1937. This is Aseptic ~ Efficient ~ Convenient. The nebulizer working parts are entirely of glass. <p> The Nebulizer was evolved specifically for using only a few drops of liquid; it can be corked to prevent evaporation or contamination of the contents.....<p> This has the original glass piece and the rubber ball with the yellow piece that leads to the black rubber tube which is shorter than shown on the box. It also looks like there is a small -stopper- that is not present. <p> Great vintage medical item.
Manufacturer: Parke Davis
