Enamelware pieces such as this one were sold from the 1920s into the 1950s. I have a $2 bill to show scale.
The ticket office at the Rose Bowl Flea Market gives out $2 bills for change. One of my coworkers gives her kids $2 bills for here kids for when they lose teeth so I am also the Tooth Fairy.
Back to the funnel it is 3" across at the wide part of the mouth and an 8th of an inch at the narrow end.
It has a loop to hang it from a hook but it wil be sitting in my enamelware strainer dish.
