I found an old copy of the Scott's standard postage stamp catalog circa 1940's and is all virtual. I found it on Archive.org for those of you that are familiar with that treasure trove of material you know what a valuable recource it has been to our hobby. (Also Google books is a noteworthy contender too) OK here is the link. broadband connection is advisable as this is a big file for dial-up. http://www.archive.org/stream/scottsstandardpo00scot#page/56/mode/2up
I do not collect US but detail as this for those who have not got the nitty-gritty of US material something to study, thanks for sharing. Erich
