All the talk about Deegam I came across the connoisseur album site and after a quick look I downloaded the 11 chapters as PDF's, is this a good resource to have as an interim to getting the Deegam CD.
What are your thoughts on this resource?
Connoisseur is quite good.
Douglas G.A. Myall - who sadly died last year - set up his catalogue system that looks at the technique (printing, paper, phosphor bars, etc.). He ignores shades. Connoisseur, that is used by John M. Deering, a dealer / new issue service provider who writes "Machin Watch" in Gibbons Stamp Monthly, also discerns shades.
An advantage of Deegam is that you will find all listings of a single value together. Connoisseur requires you to identify paper/gum/printing technique type to find the listing. This may not be very helpful when you collect used Machins that no longer have gum. Deegam also is more encyclopaedic than Connoisseur. It, for instance, also lists the Hong Kong issues with the Machin Head.
