I have a cast iron farm bell the total measurements are 12″ high and 6″ wide, the bell measures 3″ high, the base measures 14″ around the bottom, and the piece used for ringing is 4″ long. A small cow is mounted above the bell, it measures 3 1/2″ high and 5 3/4″ wide. I have looked all over but I can’t find a maker’s mark. It has rusted in some areas, it has a small piece broken off of the mounting at the back where the cow’s tail is, it has a beautiful sound, and is a beautiful piece. The bell was casted as one piece.[attachment=1:3vrjypix]farm bell 024.JP[attachment=0]farm bell 005.JPG[/attachment:3vrjypix]G[/attachment]
I’m not an expert, but I believe this to be a slightly earlier version of bells still being sold today. If you check out:
you will see new bells of very very similar design and size.
I suspect, from the bracket itself, that you are looking at a bell about 13 years old +/- 5 years (just to hedge my bets), that has been mounted outside in a moist environment. Probably used as a dinner call bell.
I think that these bells typically had a very nice tone, and it looks like you have a nice treasure there, even if it’s fairly new as far as bells go.
