I have some sort of what looks like a butter chiller of some sort, It was made by J.F. Curran Circa 1870, I have not had any luck in guessing exactly what this is! On the bottom it has the stamp "J.F. Curran & Co. Extra Plate, New York, New York and what I’m presuming is a model number stamped on the bottom of 1380. I am enclosing as many pics as this site will allow and any help will be greatly appreciated!
Approximate value would be a great jump off point!
I have more pictures to show and will reply to my email, firstname.lastname@example.org
