Found this is a pile of GB covers I set aside for an article on British War Economy Label covers for my local stamp club which is why I picked it up in the first place.
It has a very interesting Overseas H.G.R,C,A,F. Franking stamp that I have never seen before, not surprising although I collect Canada stamps, I specialize in GB.
I cant seem find a lot of other examples or any information on this. It is certainly interesting and I plan to add it to my collection, but is it rare etc......
