I am a member of several specialized philatelic societies and would strongly advise you to check out what is available and join those of interest. The making of new friends and access to expertise through the publications and networking opportunities presented by membership in these scocieties has added immeasurably to my enjoyment of this hobby and to the quality of my collections. The Societies listed below represent only a few of the choices available to those interested in KGVI stamps, postal stationery and postal history. I can recommended them all without reservation. Included below are links to some stamps dealers and auction houses that I have found to be reliable and worth your attention. There are many others too numerous to list. Postal History dealers who I can particularly recommend for expertise, reliability and quality material include Chris Rainey (chris@chrisrainey.com); Dann Mayo (dannmayo@worldnet.att.net); and Mike White (MikeWhiteUK@aol.com)
