We now manufacture this beautifully made swivel top Powder Measure. It works GREAT and is accurate. 
 
It is stamped on both sides with 5-grain increments on one side and 10-grain increments on the other side. Also, the funnel is riveted on with a tension spring unlike others on the market that use a nut and bolt (which can come loose and fall apart).
 
Ours is AMERICAN MADE with pride! Made from solid brass
