I believe the font they use is Palatino. I know they use Times Roman Italic for the Scott numbers. I think the problem is, the font used us expanded, so each character is wider than the expected width.
Scott sent me a PDF of one sample page from a Scott Minuteman album.
Here's what I can see when I open the file and look at the fonts:
Country name on top of page: Palatino 10.5 pt Bold.
Year under country name and other text visible after stamps are mounted: Palatino 6.5 pt.
Scott number: Times Roman Italic 6.5 pt.
Here is what a Minuteman page looks like:
