A few times, I’ve pointed out a web site run by Brian Costley, http://www.wheelpost.com. Brian worked for Sargent & Greenleaf, and his web site had many S&G documents that were otherwise hard to find. It now appears the web site has gone away.
Does anybody know about Brian himself?
For the record, his site was backed up by archive.org, most recently in November of 2019. So these documents are still available.
