These Door Bell Sets are a unique way for your visitors and guests to let you know they have arrived! The Lighthouse set has the Island Pasture Bell® to ring, with it's light dulcet sounds. The Bear and Moose Door Bell Sets have the Mt. Battie Wilderness Bell® , carrying out the theme of the wilderness. Then there is the "Old Fashioned' Cow Bell Set, and this one is definitely an attention getter with that memorable 'clanking' sound the cows had on their necks coming home for their milking and sustenance!
