Breast Pump Glass Portion 1890s . Condition is Used. Shipped with USPS Priority Mail. This is a Rare find intact as most are broken pieces that I have found. It is a beautiful amethyst color and has a ground top where the rubber bulb was placed to squeeze- about 5/8 inches across. The part that would be placed across the breast is about 2 1/2 inches across. It is 3 3/4 inches tall. This has a little hazing inside and a very nice antiquity to add to your collection.
