But to give proper credit, I believe his disk and some of the information within, is based upon the research of Iain Dracott who published 3 part article on the Victorian Bunheads several years ago in Coin News (? not at home right now, and I'm not sure if that is the name of the monthly magazine)... I have expanded my collection to include the Dracott varieties and even some newer prior undiscovered varieties... (i.e. Gary Bretts 1861 R/B in BRITT, my 1873 obv 7 rev c#, etc) That being said, it is an invaluable reference disk to have... a tool that no Victorian Bunhead collector should be without...
