This is a very cute little LeFaucheux 7 mm pinfire D.A. revolver, which is about 30 caliber. It retains over 75% original blue finish and has very good mechanical function and index. The bore is very good, bright and shiny with strong rifling. The fancy guta-percha grips have nice checkering with one little spot of ware on the left lower grip and no chips or cracks. This is numbered 17 and is matching. LeFaucheux is marked on the barrel top.
