I have a vague recollection from several years ago of a number of 'powder carriers' appearing on the market and the general consensus seemed to be that they were modern imitations of historic artifacts. Not even made up to deceive, just a 'neat thing' for people to buy and research the story of if they felt so inclined.
I worked briefly in a store which sold to reenactors, everything from sewing patterns to muskets, and to the general public we sold a lot of repro. stuff. Very big for a while were brass compasses, map dividers and even sextants, copied from 19th century originals and made in India. Nobody I know was fooled, but I not infrequently see them advertised in garage sales as 'antique'. For what it's worth!
