Charlie Serbian army had few battery St Chamond 155 mm howitzer in 1917 and 1918. In the second half of the twenties in the factory in Kragujevac howitzers were brought to a standard of 155 mm howitzers Schneider Mod 1917.
In the finland book of Jyri Paulaharju "Itsenaïsen suomen Kenttätykit 1918-1995" edited by Sotanmuseon julkaisuja 1/1996, the author describes all the finland guns used by the Army of Finland. Unfortunately, the finland language is quite difficult and I have not understood all the text! I do not understood if the "155 mm ranskalainen raskas haupitsi vuodelta 1915 (155 H 15)" (which is the name of the french "obusier de 155 mm modèle 1915 Saint-Chamond") is a french sending for aid the Finland during the war against USSR ("Winter War") or a sending after the french defeat of juni 1940. The certain fact is that finland Army had the following numbers of "obusiers de 155 mm Mle 1915 Saint-Chamond" in service: -19 july 1940: 24. -01 july 1942: 24. -01 september 1944: 24. -31 august 1951: 24. -15 february 1962: 24. A very long life for these old "obusiers"! Yours sincerely, Guy François.
