There is an article by James Hutchins and Fred Gaede in the Spring 1992 issue of MC&H entitled "Notes on Picks & Brushes". It has 6-8 pictures of Pick & Brush sets from the revolution through about 1841. It also has extensive bibliography to the primary literature.
PS -- Why does everyone change the proper American spelling of Accouterments to the British spelling of Accoutrements, even when referring to American stuff?
