Horse Drawn Polish Biedka wz.33 with CKM wz.30
The Biedka wz.33 was a two wheel carriage, typically horse drawn, used for moving light and heavy machines guns, light infantry mortars, supplies, communication equipment or ammunition. It could be drawn by a single horse which allowed it to accompany infantry in most terrain.
The CKM wz.30 was a Polish heavy machine gun based on the Browning M1917A1 and developed in the early 1930s.
