Between 1754 and 1755, Dieskau designed a new 3-pdr which replaced some of the older material. However, during the course of the Seven Years' War, no less than six different models of 3-pdrs were used, including the old M1717 piece as well as some 38 Saxon Quick-Firer barrels captured at Hohenfriedberg in 1745 and adapted to Prussian style by end of 1750. In addition, captured Austrian guns were also fielded.
