From a report at the link below:
The revolver with which Vincent van Gogh is believed to have shot himself is to go under the hammer Wednesday at a Paris auction house.
Billed as "the most famous weapon in the history of art", the seven mm Lefaucheux revolver is expected to fetch up to 60,000 euros ($67,000).

Van Gogh experts believe that he shot himself with the revolver near the village of Auvers-sur-Oise north of Paris, where he spent the last few months of his life in 1890.
Discovered by a farmer in 1965 in the same field where the troubled Dutch painter is thought to have fatally wounded himself, the gun has already been exhibited at the Van Gogh Museum in Amsterdam.
