Antique Medical Device Spray Bottle Nose & Throat Sprayer - Rectangular Bottle

Description

This antique medicinal sprayer belonged to my grandparents.  I'm not sure what year it is from, but it has been stored away for a very long time.
The bulb pumps air, but I don't know if it draws liquid up through it.
No cracks in the rubber bulb.  No chips or cracks in the glass bottle.
See photos for details of this item and its nice condition.
Smoke-free, pet-free home.
