Civil War Confederate Kerr revolver Tool

Something that one might not see for sale in a very long time- or lifetime; a Kerr Revolver tool. These tools were issued with the Kerr revolver for CS (and US) use during the War. This example was modified during the period for another weapon (which I'm not sure of at the moment). Either way, these are extremely rare, and hardly ever come up for sale. Would pair nicely in a cased set, or simply with a gun tool collection.
