1860 British "Pad" bit with "C" boss: Most of these 1860 pattern British army "pad" bits are found made of cast iron with and without a boss of some kind. A few are found of brass like this one with the same pattern "C" boss. These "C" bosses are also occasionally found on bridles. For more information and photos of this and other pattern British bits see the book "Confederate Saddles and Horse Equipment" By Ken R. Knopp (see home page).
