I have a bronze 12" fire bell exactly the same size as yours. It sat on top of a totem pole which fell over and damaged the stand. I took it to a machine shop to see if they could straighten it and they broke it in half! So I need a new stand and clapper.
Are your stand and clapper brass castings?
Can you make them in Bronze?
Can I get them with out the chrome plating?
What is the over all height?
What is the thread size of the hole in the top?
