The rifle in the photographs is not a
French Lebel, it is a
Portuguese Kropatschek.
I apologize for the wording in my previous reply, I wasn't trying to convey any uncertainty. The cleaning rod mounted on the side, the finger spur behind the trigger guard, several features visible in the photo clearly identify the gun. The Lebel rifle was manufactured during the
Third Republic, it would never have a crown marking on the barrel. I can't think of any French guns that ever had a crown marking for that matter, don't recall ever seeing one, but I could be mistaken on that.
I would guess that the fellow that bought it, and the auctioneer for that matter, was confused by the finger spur as they usually appear on Jaeger rifles. Unfortunately for him, they also appear on other rifles like the Portuguese Kropatschek that he purchased. The distinctive upper handguard further identifies it as the colonial version introduced in 1889. It is very unusual to have the barrel bands run under the upper handguard like that. It attaches by spring clips and was intended to protect the hands from hot barrels in tropical climates. See
Bolt Action Military Rifles of the World, pages 248-252. Although why exactly they would have thought the barrel would get that much hotter in a tropical climate is something of a mystery to me, they get pretty hot from firing as it is.
