Finland purchased 50 French 25 mm &lt;a href="25%20mm%20APX%20mod%C3%A8le%201937"&gt;APX M/37&lt;/a&gt; anti-tank guns during the Winter War through Aladar Paasonen, but only 40 of them were delivered in February 1940 through Norway. The remaining ten guns were captured by the Germans when they invaded Norway in the spring of 1940. About half of the guns, which had arrived during the Winter War, saw front line service and three of them were lost in battle. During the Interim Peace the Germans sold 200 captured guns to Finland. 133 of them were model M/34s and 67 were model M/37s, and they were designated 25 PstK/34 and 25 PstK/37, respectively, bearing the nickname of ""Marianne"". They then served in the Continuation War, until being withdrawn from front line service by 1943.
