Powder Tester (Probably French or Belgian) (AH4841)

Powder Tester (Probably French or Belgian). These were used to measure the viability of black powder. The small amount of powder is placed in the barrel. A percussion cap is placed on the nipple. When firing the tester, a wheel with graduated numbers from 1 to 10 covers the muzzle, rotates to a number. A “10” would be an excellent reading for very strong powder. Very well made tester in excellent condition.
