I received this today in a mailing from a group of collectors in the Kent Federation of Philatelic Societies.
It is from the collection of Eddie Shilling of Medway Towns Philatelic Society and forwarded to collectors in Kent by Michael R Thompson who runs his [url=http://www.KentPhilately.weebly.com]www.KentPhilately.weebly.com[/url] website for collectors in Kent. I thank them both for this item - I have not seen or heard about it before.
Mike :)
