Al,
It's like anything else; just takes a bit of experience.
Try this:
1) go to archive.org
2) at the top of the page it'll say Wayback Machine, and next to that will be an open search box that says "enter URL or keywords"
3) into that box enter http://www.perardua.net/pipes/GBDlines.html and hit enter or return
4) a search result will then appear that says this page was saved 96 times between March 3, 2001 and February 3, 2017
5) below that is something that looks like a ruler broken into years, with black verticle lines showing the captures in each year
6) click on a box (I.e. a segment of the "ruler") to highlight a given year, and below the "ruler" will appear the twelve calendar months in that particular year. Blue bubbles show which dates in each month were captured
7) click on a blue bubble and you'll be brought to the page that was captured on that day in that year
NOTE: recent captures may have been after the webpage went down, so to play it safe pull up an earlier capture. For example, for Hannah's page first click on the year 2008 in the "ruler" above, then click on the blue bubble on July 6th. That'll take you to what the page looked like on that date. Here's a direct link to that page: https://web.archive.org/web/20080706185144/http://www.perardua.net/pipes/GBDlines.html
Also note that in order to capture the various links you sometimes have to try various dates for the capture. Likewise if you're looking to see how the material on the webpage evolved over time you can do this by pulling up sequential capture dates.
That explanation was more wordy than I wanted it to be, but let me know if you can now see the GBD page by Jerry Hannah.
