Vintage School Or Boat Bell

Excellent condition, recently bead blasted because it was originally black and I wanted to see what was under the patina. I’m assuming the bell is copper because there are already green patina places on the outside of the bell. The clapper is also copper. It is unknown what metal the removable bracket is but assume a cast iron. This piece is vintage from a Texas estate and not know what the original use was but it’s a very cool piece! The bell base is 6” diameter and 5-1/2” tall. A large bell! The bracket is 10-3/4” tall and nearly 4” wide at the top. Overall, it is 14” tall. My price is very firm. No embossing or writing on the inside or outside indicating a manufacturing date or maker.
