How many times does the venerable "soixante-quinze" need to be listed?
No French light bomber, such as a Breguet 693?
The designation is "FM 24/29" (or "fusil-mitrailleur mle 1924 m. 1929")
It wasn't a MAS design, AFAIK.
I don't think such combination ever existed. The postwar FSA MAS 49 was sometimes fitted with a scope, but for the 1940 time frame, the Lebel seems to be the only choice:

No French AA gun either? Unless the Oerlikon is listed as such.
