Today I received a lot I won on eBay
Sunday night. It was listed as an "interesting WW collection in Harris Statesman album." From the image, though, it was clearly not a Harris album.
In the description the seller did describe it as a Scott International. Upon opening it I could not believe how thick the binder was. Turns out the pages cover part 4 and what seems to be an older version of part 5 with pages to 1965.
All in all a pleasant surprise, especially as both seem to include the U.S. pages. I have yet to be so lucky with a couple part 2 collections I've purchased.
