I am trying to determine the different calibres of rimfires that C. Fusnot made. These are brass case usually with a dished base. The rounds I want information on have a raised headstamp around the outer part of the bottom of the rim. It will say either C. Fusnot Breuvelle or just Fusnot Breuvelle. I currently know of three calibres that they made, but would like to hear from anyone who has any specimen. A photo with dimensions, on the forum, would be appreciated. This is for research only. Any pictures of boxes would be fantastic.
