Description
I think these cartridges were likely made by Sellier & Bellot. They were potentially made for Eugene Lefaucheux to sell at his shop.
One recently sold for $260 before buyer’s premium after 32 bids at an Engel’s Collectible Auction: https://www.engelscollectibles.com/Listing/Details/501535/9mm-Pinfire
