This is a bit closer to the type of bell and hardware I would expect to see. And this one is mid-1800s.
http://seattle.craigslist.org/sno/atq/2845210699.htmlFirst things first - this bell unfortunately has a small crack on the lip that goes all the way through. This obviously affects the value seriously, it would probably be worth well over $1000 if it had no crack. I have no way of knowing how the tone has been affected, but it still rings very nice to my ears. With that out of the way here is more info!
I really didn't know anything about these old bells except the basic knowledge. People call these bells brass or bronze, but really they are a special alloy called "bell metal" which is about 4:1 copper to tin. It gives bells a much better tone and resonance than the other metal mixtures. Pretty much all the info I got on this bell was from a bell collector forum which is this:
The iron rod and rope pull are original. The bell probably dates to the 1830-60 period. It could have been used on a church, school, fire station, farm or plantation, riverboat, or in any public place requiring a bell. More than likely it was not used on a locomotive (wrong mounting) or ocean vessel (stationary instead of swinging). The bell has some features suggesting a Stuckstede bell. The yoke is a bit unusual as it does not fold around the crown and may have been fabricated somewhat later than the original. The clapper attachment suggests a bell from the mid 19th century.
Here are the specs: 40 lbs, 12" diameter bell, 8 1/4" height (just bell), 11" height total, and yoke is 21" wide. Has a great green patina with some rust and other discoloration. It would make a great functional bell as-is or would look awesome polished and mounted. I would normally never recommend removing the original patina but since it is cracked it would be a better candidate than an intact one.
