Looks like you are on your way to finding the provenance. Ask @lrv. He lives for the hunt and may have the original new product sheet digitized. Garrison and/or Murray can be reached if you are persistent. Remember, it isn't what you know but knowing where to look to find the answers! Eric may also know someone who knows someone who knows.
