105 mm field guns, designed by French Schneider, were a mainstay of Polish long-range artillery at the outbreak of World War II, despite their range was lower, than of newest opponents of the same class. The first one, designated as 105 mm armata wz. 1913 (wzór 1913 - 1913 Pattern cannon) was a popular French canon de 105 mle 1913 (or L 13 S) from before World War I, used by several countries thereafter. The 105 mm armata dalekonośna (long-range cannon) wz. 1929 was Schneider's newer export model, differing among others in a split-trail carriage and longer barrel, resulting in longer range. The latter one was also manufactured in Poland. Their abbreviations are also sometimes shortened to wz. 13 and wz. 29.
