Tony,
I can't help with catalog pages, but I will offer these links to my site that may be of assistance.
The
Search the Collection page allows you to enter criteria (color, face value, etc.) in an attempt to help ID the stamp. The catalog numbers shown are typically Michel and Scott. You can click the
Details link to see more, or the
Link link to see the page for that stamp/set.
You can also browse the collection to see the pages for the individual stamps/sets. The page for that era is
here, and the links to the individual stamps/sets are under the menu at top right entitled
Postage Stamps. To see Scott numbers, click on the thumbnails of the stamps.
