37 mm/48 (1.46") AA Gun Model 1935
Updated 22 May 2008
Experiments with the semi-automatic 37 mm Model 1933 AA gun resulted in the much improved fully automatic Model 1935.  However, this weapon did not finish development before the French surrender in 1940.  One of the few prototypes was mounted on the old Patrol Sloop Amiens and was apparently successfully used during the Dunkirk evacuation.

Each gun had a pusher hoist for six-round magazines.
