11mm73 six-round cylinder, top break double action, star ejector.
This revolver was won by Marie Joseph Chatelain, a future WW1 French general. Marksmanship contests were very common during the Belle Epoque, and gave rise to a number of fancy small arms being made in standard issue calibers - like the revolver 11mm73 round for the MAS Mle1873 revolver - to be won in them.
