This is a nice old unusual small galvanised chicken drinker.It measures approx. 3.25 inches across,is 4.5 inches front to back and stands 6.2 inches in height.The piece probably dates to the first half of the 1900s and is in pretty decent used condition with some light wear commensurate with age and use as shown.Thanks for viewing and please take a look in my shop for many more interesting items.
